G7 Backs Fresh Oil-Gas Sanctions on Russia as Trump Pivots Back to Ukraine at Évian Summit

Great-power wars often hinge on whether alliances can outlast an aggressor’s industrial depth: in 1918 the Allied naval blockade, not the Western Front alone, cracked Imperial Germany’s resolve; in 1941 the U.S. oil embargo pushed Tokyo toward desperate escalation. By reaching for a 21st sanctions round that explicitly targets LNG infrastructure, the G7 extends a decades-long trend—begun with the 1973 Arab oil weapon and refined in the 2014 Crimea sanctions—of using energy chokepoints as tools of coercion. Trump’s re-engagement illustrates another cyclical pattern: every few years European security still depends on whether Washington is attentive (Truman’s 1948 Berlin Airlift, Obama’s 2014 reassurance, and now 2026). If the G7 sustains this pressure while Russian recruitment falters, the war’s economics may tilt irreversibly; if not, history may record this summit as yet another rhetorical high-water mark. On a century scale the episode underscores a slow but clear structural decoupling between Russia and the Western-led financial-energy system, a shift likely to outlast the fighting itself.
