Putin has withstood the West’s best efforts to reverse his invasion of Ukraine, and his hold on power is firm. The U.S. and its allies need a new strategy: containment.
I haven't read the article, but yes, wars do have time-limits:
Once a war becomes domestically impossible to participate in, Vietnam as 1 proof, then the-course-of-war changes.
Economic-collapse means that Biden's hosed in 2024, and the Republicans are Russian allies, not NATO allies.
Yes wars have time-limits.
Simply wait & see: by the end of 2025, NATO will be gutted, Trump will have been crowned GEOTUS ( a term they already use for him ), and Trump will ( passively, at least ) back Russia.
Sickening, but it looks like that's the fact of the unfolding global/geopolitical near-future.
