I’ll preface with saying that I’m only a random Communist. Please take what I say with a grain of salt, even if I come off as confident.

Regardless of your opinion on the war, it is not going to affect its course unless you go fight there, with a few exceptions.

Unless you live in Russia or Ukraine, your priorities should be:

• pressuring your country’s government for non-interventionism, including sanctions. Capitalist States have only the interest of capital in mind, and their intervention will hurt the people further
• fighting racism in your communities, especially the new wave of anti-Russian hate.

If you live in Poland or Romania, you should also be fighting the racism against non-Ukrainians (mostly foreign students) seeking refuge. Most of them just want to go home. The fact that the police are attacking them is extremely ridiculous.
