there will always be wars; my point is that you'd think the world would have figured out by now which ones to get involved in, and which ones to avoid; from a historical standpoint, getting into war over political/border disputes rarely ends well; If getting involved in Ukraine leads to a bigger war in the future, another world war later, then the losses incurred in the current one will seem insignificant by comparison.
It's naive & shortsighted to get involved in war to save a few thousand that only creates more enemies if/when it leads to a major war that kills millions & destabilizes entire countries...
We're still suffering the fallout from the USSR's collapse in '91; with the abundance of black market arms trading, militant groups and terrorists sprang up everywhere, it created a power vacuum for 2nd and 3rd world countries.
Only a fool would think pushing Russia into another collapse would somehow benefit the world, especially if the west bankrupts itself in the process and plunges the world into complete anarchy...
