They shouldn't be, but the actions of past presidents have made it so. For instance, Obama's sanctions caused massive damage to the Russian economy, and the Bushes/Clinton flagrantly violated their promise not to extend NATO beyond the borders of Germany by getting most of Eastern Europe into NATO. Because of that, NATO troops are now stationed dangerously close to St.Petersburg (in Estonia) - and Russia would certainly want at least a bit more buffer room between its core and NATO bases. It's also why they took Crimea after Maidan - they didn't want a US ally to control such a vital piece of territory just adjacent to core Russian territory.

I bet that all of that could be fixed, though, aside from the NATO thing, unless NATO ends like it should. I believe Trump said something about that.
