Not stepping in is exactly what is going to cause a world war.

So you would prefer the war in Ukraine to go nuclear? This isn't a hypothetical.

What is even less hypotethical is that dozens of countries are now actively making plans to arm themselves with nuclear weapons, as the US refuses to take the risk to step in.

Dare to guess what are the risks of nuclear war (even by accident) when that becomes the new normal?

The Russian aren't going to make less nuclear threats if the US keeps folding.

And the United Kingdom and France didn't want to start a world war over Austria or the Sudetenland. Appease Russia/Iran/China at your own peril.

We have to let bad people take the important step of attacking before we defend. Otherwise it becomes thoughtcrime.

The US could've and still could flood ukraine with weapons. It wouldn't even be the first proxy war between the US and Russia.

where does this logic stop? At whose borders?

Because if Ukraine falls I can guarantee you that first it will be minor incursions into Poland and/or Baltics airspace. Then false flags attacks. Then more. Each time testing "escalation management" and sewing disagreements into political scenes in the West. Then more.

putin has said many times that he considers collapse of USSR the greatest tragedy ever. He wants revenge for this. And he is getting it.

No.

The American right wanted to score political points on Biden and refused to pass a very popular funding bill.

The consequence has been one of the most pointless, damaging failures of American policy in a very long time.

It's one of the most shameful things I've ever seen.

They're referring to the sudden end of support for Ukraine, done at the behest of Donald Trump. Republican lawmakers were actually considering continuing it until he demanded they not do so.

That’s how you start a world war. Once US is perceived as weak and indecisive all kinds of genocidal monsters crawl out to do what they want.
