I don’t think for a minute that they’re all paid trolls. Many I’m sure are simply out of their minds, or totally ignorant on KGB/FSB history.
When my son deployed, we had to attend a lot of pre-deployment informational meetings. They stressed that Russia was still one of the top 2 security issues for our country. I sometimes forget that. I hope folks at least consider that the Russians may be playing both sides, just as the US has played both sides (and probably is now as well).
That said, I don’t mind if the whole world joins together and wipes out IS.
