Lots of increasing geopolitical drama and it probably won't end anytime soon.
Our sanctions regime crashed their economy (or at minimum, exacerbated their long running problems). It's difficult to say "little to challenge them".
First the illegal annexation of Crimea was "complicated," and now the Russian economy isn't in a freefall? Where are you getting your news?
Do you have a more specific source?
Russia has 3 foreign military bases. We have something like 600?
We have announced plans to spend a trillion dollars on more nuclear weapons, and we are placing a few of them near Russia's borders - as far as I know they are not placing weapons along our borders!
Who profits from this? So obvious that I won't even name the usual suspects.
The U.S. spends a trillion dollars on nuclear weapons per 20 years. [1]
I agree that disarmament is a credible and the optimum mechanism for reducing risk of the use of nuclear weapons in war and in testing. I think that using hyperbole discredits earnest efforts to this aim. The broadside against secret profiteers ("the usual suspects"?) compounds this.
