Because Jesus Christ they’ve been fighting each other for centuries. The Middle East has always fought amongst themselves. Nobody is ever happy. When the country is fight with itself there’s nothing we can do. There is no right and wrong. But Ukraine has not been a part of Russia for a very long time. And it’s been operating independently for a very long time… PLUS THET MADE A TREATY. The promise that Russia would leave them alone to deal with their own issues if they gave them all the nukes. All the other countries that were fighting, non of their leaders are threatening to nuke anyone.! You got Mr. happy nukes over here threatening everyone around him if they didn’t follow his ideas. He has zero say in what and how other countries operate. Syria wasn’t trying to invade Iran. Irans not trying to invade anyone. ( not yet) Iraq we’ll see he tried and then he got fucked up.
