That's exactly the problem, dumbass. The US is "helping" Ukraine against Russia, both non-NATO members. While "helping" Israel bomb the shyt out of Palestine, both non-NATO members. Article 5 is triggered when a member state is attacked. Doing what America is doing is literally going against its own rules and the rule of law. It's a double standard that everyone else NOT in NATO calling out. Now even NATO members are calling it out.
Even if you think the US is helping Ukraine, the crux of your argument is Donald Trump's argument. Which is, we're doing them a favor by doing all this shyt. We don't have to, so we won't. NATO can take care of it on its own.
