A nationalist Russia is simply not the reincarnation of the USSR. Russia is not a serious ideological or military threat to the West. The West should be more concerned with its own economic, political and social well being.
True, in terms of geopolitical behavior it's actually closer to the old Russian Empire.
Russia is not a serious ideological or military threat to the West.
Certain pieces of "the West", say, Estonia, are not going to agree with the latter 1/2 of that. And if Russia is not a serious military threat, then, from a military standpoint, why not put troops in, say, Kherson, Ukraine, as a tripwire?
As for ideology, I am not so sure: We are as a whole more decadent and soft, not to mention divided, no?
More important though, is that any current Russian "threat" is relatively irrelevant. What will kill us is the logical progression of events if the US, and especially its people, are found to be lacking will and integrity, both by those with whom we have security agreements, and by those who are restrained in their agression by those alliances.
The West should be more concerned with its own economic, political and social well being.
Lack of either internal or external focus will be our ruin.
