If you've been paying attention, it's patently obvious foreign involvement in the Ukraine-Russia (Russia-Ukraine?) war is on the rise. Rhetoric, sympathy, financial and humanitarian aid is all well and laudable. But then there were the sanctions against Russia, then small arms and intelligence for Ukraine, then drones, then howitzers, then Western government boots on Ukrainian soil (for help "training" Ukrainian forces), then tanks. And as this is a war, it would be weird if there weren't other forms of aid we didn't know about.
Maybe the West has Russia figured out. Maybe they know something Russia doesn't. But I do know this, nothing goes according to plan, especially in war; and leaders have a tendency to be dumber than they appear. The West is gambling in a dangerous game. I obviously don't have the whole picture, but there is a line and given this sustained escalation, at some point it will be crossed.
