What two countries hate each other the most?
I bet my money for them:
Armenia and Azerbaijan hate each other, the most in the world.
Maybe we have Iran-Saudi hate each other, India-Pakistan hate each other, China-Japan hate each other, Serbia-Albania hate each other or Chile-Peru hate each other. But none of them can never be counted into like Armenia and Azerbaijan.
Reason why? Read:
Upon the disintegration of the Transcaucasian Federation with the proclamation of the independent Democratic Republic of Georgia on May 26, 1918, both Azerbaijan and Armenia proclaimed their independence on the same day, May 28, 1918. Both Armenia and Azerbaijan laid claim to territory which they saw as historically and ethnically to be theirs, these territorial disputes led to the so-called Armenian–Azerbaijani War between 1918 and 1920, a series of conflicts that ended only when both Armenia and Azerbaijan were swallowed by the Soviet Union.
In 1988, the Armenians of Karabakh voted to secede and join Armenia. This, along with massacres in Azerbaijan resulted in the conflict that became known as the Nagorno-Karabakh War. The violence resulted in de facto Armenian control of former NKAO and seven surrounding Azerbaijani regions which was effectively halted when both sides agreed to observe a cease-fire which has been in effect since May 1994. In late 1995, both also agreed to mediation of the OSCE Minsk Group. The Minsk Group is currently co-chaired by the US, France, and Russia and comprises Armenia, Azerbaijan, Turkey, and several Western European nations.
After the war, relations between Armenia and Azerbaijan remained very tense. In 2008, Azerbaijani president Ilham Aliyev declared that “Nagorno Karabakh will never be independent; the position is backed by international mediators as well; Armenia has to accept the reality” and that “in 1918, Yerevan was granted to the Armenians. It was a great mistake. The khanate of Iravan was the Azeri territory, the Armenians were guests here."
Entire of two countries have been shaped with the darkness of history. Azerbaijan is Turkic state, close to Turkey, a country which Armenia sees as an eternal enemy due to Armenian Genocide.
Azerbaijan considers Armenians are the immigrants in Caucasus. Armenia also sees Azerbaijanis the same. Since then, two countries often go to clash and fight. The newest was the 2016 clash.
Armenia and Azerbaijan don’t even have diplomatic missions on each other.
Then, yeah, why not them? Just because they are too small, doesn’t make them irrelevant on this list.
