Answering your picture: It's because Syria and Mexico aren't perfect paradises like the United States. There are many things in those countries that need to be solved through warfare.
First people in Malvinas were french. Spanish asked the to gtfo and french agreed. Then, those spanish people were taken out by force (they did not accept to gtfo like the french did) by the british. Those spanish people are nowadays what we would consider argentinians, because Malvinas were part of the virreinato. So fuck off, you took them by force and then used the excuse of a war made by Argentina under a dictatorship government to keep them. If Kelpers wanna be english, go live in England.
