It's certainly a charged event with emotions running hot. People are going to say things that are wrong.
Crimea was a difficult subject because they are ethnically russian. Due in large part to a gigantic naval base. They did vote to separate from the Ukraine.
That was then, today is different. The direct invasion of Ukraine is aggression. Putin lied, diplomacy has failed.
As emperor of canada I would have done what my gov has done so far, but also put a sunset. In 1 year, unless something changes, we end any and all connection to russia. their citizens may not come here. none of their citizens may own property here. Absolutely no trade of any kind. Anyone who is currently doing business with them, your contracts are null and void. Find new suppliers.
