The sanctions are because congress forced them. Trump fought them.
I'm sure you'll also give congress the credit for our increased military spending.
perhaps congress fired the cruise missiles at Syria for the use of gas? ( Obama's red line)
congress evicted 60 diplomats?
Congress forced Europe to spend more on nato?
perhaps congress called out Germany for negating the effects of our sanctions by working a back door pipeline deal?
anyway you want to spin it , trump has taken many positions that are counter to Putins interest.
anyway you want to spin it , trump has dramatically increased the accountability applied to Russia and its interests.
if your concern about Russia is actually legitimate and not political posturing that you should be mad at Obama for being a puss and grateful that Trump has applied much more pressure and accountability to Putin.
I will now sit back and await as you bemoan the weak ineffective leadership of Obama .
