The "strong and deep statements" they release are cheap theater.
The US is defending Europe through NATO. Until that changes, the EU will continue to be the US's slave.
The RU/UA war was entirely orchestrated by the US. The "Russia will invade the EU" propaganda was useful to scare the EU population, so they'd accept issuing 800B of debt to "rearm Europe" (buying from and enriching American war companies). Debt that will be paid using EU taxpayer money of course.
The US government is using their own taxpayer money to buy weapons for Ukraine (money++ for politicians and their war company friends), and then they forced the EU to issue 800B of debt to further enrich their war company friends.
Why would the US defend the EU from the Russian invasion, with this insane war revenue?
