True. But then again, that was a clear retaliation response to an action by Obama:

Shortly before leaving office, Obama ordered to increase tensions with Russia by expelling russian diplomats, effectively reducing the number of russian diplomats in the US to 455.

So the Kremlin did a tit-for-tat response and ordered that the number of US diplomats in Russia must also be reduced to the very same number, 455.
