there are fascists in Ukraine, like in a lot of countries

Most countries don't have a fascist government that violently suppresses the left. Israel and Ukraine are about the only ones (and maybe Modi's India to an extent?) right now.

It's not about a "right" to invade. The point is this was the only option left with a coup gov that doesn't care about prior peace agreements, kills people for resisting (like Eastern Ukrainians in DPR & LPR and Crimeans), and is being blocked by the US and UK from negotiating.

Russia has no right to carry out a genocide—any more than Ukraine had the right to carry one out on people of the Donbas for almost a decade—but then again Russia isn’t carrying out one, despite what Five Eyes governments & corporate media insist.

I will concede that there are a few fascist elements in Russia, but they aren’t in power, and one of their most well-known figures (to Westerners at least) recently died.

• 2007: Video: Alexei Navalny Compares Muslims to Cockroaches
• BBC, 2021: Amnesty [International] strips Alexei Navalny of 'prisoner of conscience' status
• Workers World, 2024: Who was Alexei Navalny? A violent white supremacist and fascist on U.S. payroll

.
Neither Navanly nor the Azov Battalion are aberrations: the US has been maintaining fascist cells in Europe our whole lives, as a backstop against Europe ever gaining a real independence from the US, or worse, becoming socialist.

The U.S. Did Not Defeat Fascism in WWII, It Discretely Internationalized It

Edit to add:

In particular, the US doesn’t want Europe and Russia to develop closer ties, because it doesn’t want the “Eurasian landmass” to ever cohere, because it would become too self-sufficient and powerful for the US to control. Zbigniew Brzezinski laid this theory out when the Soviet Union fell. That’s why the US tried to convince Europe not to build Nord Stream 2 and then later not to turn it on, why Biden said he would “bring an end to it” if Russia invaded, and why they ultimately did bring an end to it.

The US also very much wants regime change or balkanization in Russia so it can resume its neocolonial plundering of it, which started under Yeltson and ended under Putin.
