An ex-marine of country A is caught and sentenced as a spy in country B. Country A not only frequently makes open threats about invading country B, but has also invaded 2 more countries in the region in the last 10 years, one of those with a false pretext, and another to revenge the actions of a few men, not the actions of said country.
Country A, 60 years ago, had the democratic government of country B replaced with a dictator of their choosing.
Country A has imprisoned non-soldiers of other countries, taking them from their countries and keeping them in a remote prison in the tropics without even a trial. A lot of them where found totally unrelated to anything, i.e innocent, and released several years later without any compensation of course.
Soldiers of country A are known to torture, rape and beat prisoners from other countries, and even take pictures of said torture with their phones and laugh at it. Several widespread cases where made known.
Country A has weapons of mass destruction, and is the only country known to have used two of those in a war, killing hundreds of thousands of civilians, just as the war was ending and the enemy was surrendering.
Country A has made medical experiments on people without their knowledge. In one case, they publicly said they are "sorry", 40 years after the fact.
Country A is known to have very good relations with dictators and despotic governments in many countries where it serves it's interests.
Everywhere country A invaded in the last 10 years, they brought mass instability, civil tension or war and chaos, in the name of "bringing democracy". Coincidentally it's mostly in strategic places with lots of natural resources.
As late as 40 years ago, country A still practiced segregation in many of its cities. They have also assassinated their two most prominent anti-segregation activists. Even today, despite having made progress on the matter, a hugely disproportionate percentage of the black population of country A is in prison.
Finally, country A practices the death penalty as much as country B, and has a lot of religious fanatics among its population, too, and certain places even prefer non-scientific evolution theories instead of the de-facto scientific theory on the matter for their schools. It's a known fact that an openly atheist would never, as it is, get elected to the top office in country A.
Can you guess country A and country B? Would you get mad at country B?
