I think Americans in general don’t see it as a difficult choice to support Ukraine
Politicians find it difficult because Republicans are pro-russian, and both parties are heavily aligned with Israel. So Ukraines the only one really seeing any push back.
Basically we encompass everything as black/white socialism/capitalism
When pretty much every country (including the United States currently ) implements both.
And the problem is by demonizing socialism as the main economic structure, politicians basically succeeded in shaming people for any socialist policy they disagree with.
