crazy, you are going into some complicated question ignoring simple facts. R Twersky writes that the hardest to treat are smart alcoholics – they can always convince themselves why they still can’t drink. So, you seem to say that bad things during Biden are due to Trump, during Obama – due to Bush , etc – while there is some logic here, there is a limit too.
the only place where Russians advanced during Trump times was in Syria where they were already allowed in during Obama times. Given multiple successes US had in Syria and facts on the ground that Assad survived with Russian and Iranian support, it is not clear what else US could have done.
Maybe take a bigger picture – Cato’s latest human freedom index for 2019 shows decreasing freedom between 2008 and 2016 in Eastern Europe and MidEast and stabilized from 2016. If you want, look up other indices.
