Good discussion of our strategy in Europe to deter the Soviets and Russians.

I think we need more than a "tripwire." I do agree Russia's Ukrainian approach is most likely in the Baltics.

"...These new factors, however, do not necessarily change the fundamental calculation. History suggests that leveraging American technology, developing strategies of offset, and shifting more of the ground burden to NATO allies can likely achieve the same effect as a conventional Army buildup on the continent will. If the United States’ intent is to demonstrate resolve in the face of possible Russian expansion, then to paraphrase Eisenhower, one brigade can serve that purpose as effectively as several. The Russians will always possess a conventional advantage in a geographic area that essentially serves as their backyard, and where the terrain lends itself to rapid offensives. Direct competition against an opponent in an area where they possess a clear advantage is merely foolish. At the very least, the United States should explore less costly and more nuanced options in its efforts to deter Russian aggression before committing to another buildup. In doing so, perhaps the Army can finally break free from the same myopic force structure cycle that has dominated military planning for decades."
