CIA is earning its keep. But watch out—this is a game Russia can play as well.
The Russians have been playing this game for a long time. They are active right now, see the recent string of asassinations all over the place. As for Ukraine, they dont need to risk agents. They can blow up what they want to in Ukraine with missiles.
On my part I see this as sabotage activity by Ukraine.
You mean like fires at food production facilities? With a few airplane crashes thrown in for luck?
