It's the rock and hard place analogy....
In one hand do nothing and eventually Ukraine will become a Russian state, continue with the path we are on and face WW3.....
In my opinion, the west is committed to supporting Ukraine and will continue to do so regardless of cost......so far the majority of citizens agree with supporting Ukraine.
On the other hand, Ukraine's military are like drunken sailors with a free credit card, they are quick to commit equipment and arms in fights that are extremely risky to win because they know there are boatloads of equipment and arms arriving each and every day to replace what they squandered.
The thing to remember is Russia won't back down so the west is in it for the long run.
Canada is buying weapon systems for Ukraine that we don't even have in our military (and should). Troops have been screaming for these systems for years only to see them go to Ukraine.
