In real life,
https://www.powerlineblog.com/archives/2026/07/can-this-alliance-be-saved.php , EuroLand leaders are far from laughing. Trump is arm-twisting them to actually have some capability for defending themselves (the RN cannot deploy a single full carrier battle group, for lack of operational destroyers, operational attack submarines, and possibly not even one operational carrier). Britain is an island without a meaningful navy, and Germany, France, Spain, and Italy are not a lot better off.
EuroLand leaders also know their nations’ cultures have waxed lazy about self-defense, because they’re letting Uncle Sam do it. They realize that since the US has the airlift, airtanker, and long-range planes capabilities, many US military personnel could redeploy home, with little loss of deterrence and responsiveness. HOWEVER, several 10s of thousands of American personnel going home, unreplaced, will make a lot of economic dents all over the various nation.
In short, EuroLand leaders are worried and a bit POed that Trump isn’t an Obama-Biden moosh push-over.
