the world is not binary. there are many people who bare part of the responsibility:

• the republican party - all of them
• republican voters
• the democratic party
• no-voters (who didn’t want to “support genocide” and now you have a worse genocide and a bunch of other horrible shit including a shit load of extra war crimes in ukraine for the foreseeable future)
• the media

these and many more can have played a part all at the same time
