The world has nearly 200 countries. We often hear of unique customs, natural wonders and remarkable structures scattered around the world. The tourist offices are quick to promote the exclusive treats they have to offer.
But how much do you know about which countries do not have ? Are you ready for a journey where there is nothing to see? No tickets required.
10 No army
There seems to be a constant stream of wars around the world, and 2017 was no exception. Fights are struck, countries are invaded and lives are lost daily. Of course, one of the main tasks of governments is to provide their citizens with adequate protection.
Having a military, an army, a navy or, in the case of Japan, a "self-defense force" is usually undisputed. Huge amounts of money are diverted from constructive projects and instead used for more destructive means. A necessary evil, some might say.
Costa Rica is a country that defies the trend. Since 1948 there was neither army nor military. The then President José Figueres Ferrer was embedded in the new constitution that the military would be abolished and the money would be directed instead to the improvement of the country. Education, culture and health would be as much at the center as improving police forces. 
This does not mean that Costa Rica is without problems. Within the country, there are issues such as border disputes with neighboring Nicaragua and the passage of drugs from south to north. Nevertheless, it takes some self-confidence to relinquish a military, and Costa Rica is indeed just one of over 20 countries without official forces. This is about giving peace a chance.
9 No Illegal Drugs
With Canada and many US states in various stages of legalizing cannabis, it seems that they are the leaders in the transformation of the so-called "war on drugs." The Netherlands are famous for their cafés and their liberal attitude towards marijuana. But when it comes to hard drugs, many are surprised to learn that another European country is leading in tolerant attitudes: Portugal.
Portugal decriminalized all drug use in 2001. Yes, all drugs! Even heroin and cocaine. Portugal opted for a slightly different approach to drug use and treated it more as a public health problem than a criminal one.
Since then Portugal has one of the lowest mortality rates due to fatal overdose compared to the rest of Europe. Portugal rarely records 3 deaths per million, compared to 44.6 in the United Kingdom and an EU-wide average of 17.3.  While it would be unwise to assume that this could be the only factor contributing to such a low quota in Portugal, it is an interesting case.
8 No Government
One of the prerequisites for a functioning sovereign state would be a government that would oversee all matters. In 2011, Belgium broke the world record for the country without official government for the longest time.
A total of 589 days passed without a government in office. Politics in Belgium is very decentralized, which means a lot of the daily activities went on as usual. Bureaucrats were still coming to work, and the streets were riot-free. 
Western Sahara is a country in southern Morocco, bordering on Algeria and Mauritania. It was colonized by Spain in 1884 and annexed by an independent Morocco after decolonization after the Second World War in 1957.
For decades it has been a "contested area" that claimed both Morocco and the Republic of China Polisario Front. Without agreement, and with the efforts of the United Nations, it seems that Western Sahara will continue to lack a stable government for many years to come. No Names On Stamps
There is only one country in the world that is not obliged to indicate its name on its stamps, even if they are used for posting abroad. If you're a philatelist, you've probably come across this rather unusual fact. Prepare for your prior stamp knowledge to be solved.
Britain was the first country to issue stamps in 1840. It proved very popular and solved one of the biggest problems with the postage-free payment. British stamps have at that time always shown a portrait of the ruling king or queen, and this has long been a defining feature.
In 1874, the Universal Postal Union allowed Great Britain to be the only country in the world that did not require that a name of the country be included in the design of the stamp, which continues to this day. 
6 No External Debt
Although the numbers are constantly changing, the US external debt (defined as public and private debt to non-residents) is estimated at a whopping $ 17.91 trillion in recent estimates. The United Kingdom has $ 8.13 trillion. The entire world is indebted over $ 76 trillion. In fact, almost every country in the world owes millions, billions, or trillions of those pesky dollars to others.
Although it is said that "money moves the world", it might be more appropriate to replace "money" with "debt". It does not seem possible that the economic system could work in such conditions, but even more surprising is that Brunei, a small country on the island of Borneo in Southeast Asia, owes absolutely nothing to anyone. No dimes. You have $ 0 foreign debt.
How has Brunei managed to avoid this swamp of foreign debt? Two words: "gas" and "oil". These two raw materials explain the incredible wealth of the country.
After independence from Great Britain in 1984, Brunei did very well. Brunei citizens enjoy a well-organized welfare state and have even subsidized food and shelter.  Even government debt is extremely low at 3.1 percent, with Hong Kong being the only country to do well. Congratulations, Brunei.
5 No Sphere to Call Home
London. Paris. Poland. Banana. Christmas
What could connect these words? You'll be surprised to know that London, Paris, Poland and Banana are all villages on Christmas Island. Kiritimati, which is actually a reminder of "Christmas", is located in the center of the Pacific Ocean and belongs to the Republic of Kiribati.
Kiribati is a reversion of "Gilberts", this time named after British explorer Thomas Gilbert. Having been colonized by the British and conquered by the Japanese and used by the British and Americans as a nuclear test site, Kiribati faced many difficulties.
Maybe you have heard the name "Kiribati" already for the New Year is announced. The country is at UTC + 14, so it's one of the first countries to welcome the New Year. This means that the 180th meridian expires on the opposite side of the Earth's meridian and dissects this archipelago. The equator also runs over and through the islands. So Kiribati is a very special country, as it is the only country that can be found in all four hemispheres. 
Unfortunately, Kiribati faces new challenges from rising sea levels due to the low nature of the islands. In 2014, the Kiribati President bought land in Vanua Levu, Fiji, to reduce the expected problem of "climate refugees".
4 No national anthem
The World Cup, the Olympics and every other major international sporting event is an opportunity for rivals and citizens to come behind their countries, wave their flags and sing (or mumble) their national anthems. Great Britain has "God bless the Queen", the US has "The Stars and Stripes", Brunei has "Bless the Sultan" and Equatorial Guinea has its fantastic name "Let's take the path of our immense luck"
Greece's National Anthem is called "Anthem freedom "or" hymn to freedom ". With 158 verses, it is the longest national anthem in the world.  Fortunately, the first two verses are often regarded as such. Enough
One could assume that a national anthem is reserved for a country. However, the Greek national anthem is also the official anthem for another country, the Republic of Cyprus. There it is sung since 1966. No Words
Although the Cypriots have taken over the hymn of another country, they have at least a few words to sing when the tune is played. Have you ever seen the camera panning the faces of the players at the World Cup and noticing that they barely move their lips? That could be because they are Spaniards.
The national anthem of Spain has no lyrics. "Marcha Real" ("Royal March") has no official texts, at least since 1978. Although the anthem used to have words, they were considered too "fascist". There have been some attempts to find a solution to the wordless hymn, but it seems that the Spaniards will be humbling for the time being. 
2 No grass
There are many places where grass is difficult to grow. Countries with hot desert climates may have difficulty growing grass, especially grassland, and need to use extensive irrigation resources. Nevertheless, the cultivation of grass is technically possible in these inhospitable climates.
After some unfounded rumors, it is one of the conditions for the competition in international football under FIFA to entertain a grass football field. This seems to be a problem for Greenland. 
Despite its name, Greenland is not very green. There is not a single turf field in the country, and the weather conditions make it an impossible destination. Another problem is political. Greenland is currently an "autonomous region" of Denmark. Although it is a national football team, they are technically not a country.
Together with the lack of grass, Greenland certainly has a tough job convincing FIFA. But times are changing.
1 No mosquitoes
Mosquitoes are the deadliest animals in the world. Sharks kill only about 10 people a year, hippos kill about 500, dogs about 25,000 and snakes about 50,000. In second place, people kill 475,000 people each year. However, with the transmission of diseases such as malaria, dengue fever, yellow fever and encephalitis, mosquitoes are responsible for most deaths – approximately 725,000 people annually.
Mosquitoes can be found in almost every country in the world. So is it possible to escape the annoying humming, the irritating sting and the potentially deadly diseases of the mosquitoes?
Yes, if you move to Iceland!  Compared to Greenland Iceland is much greener and Greenland is much more icy. What about the confusing name, could you ask? In short, the Vikings jumped when it came to naming the islands. In their defense, however, the climate was a bit different then. In any case, Iceland has no mosquitoes, but Greenland!
