What country has been in the most wars?

[Grant Johnson]

It's almost impossible that the United States could have been involved in more wars than any other country in the world. Even within the lifetime of the US,Great Britain and many other European countries were almost constantly in a state of war in either Europe or one of their colonial holdings.

Somalia is the country that is the least peaceful and has the most wars. Its GPI: 3.392, Political terror scale: 4.5, Access to small arms: 5, Relations with neighboring countries: 5,and the likelihood of violent demonstrations: 5. The war-torn nation of Somalia has been dubbed “the world’s worst humanitarian disaster”. The country has “not had a nationally functioning state government since its descent into civil war in 1991". There has been violent confrontation between Islamist rebel groups in an effort to gain power. The power struggle between them, specifically the Hizbul Islam and Al-Shabaab, have led to the death, displacement and human rights violations of millions of Somali citizens. Because of the constant warfare, an average of 3.25% of the population left the country each year between 2000 and 2005.
