A combative exchange over Britain's wartime legacy lands as a direct attack on NATO and the US military presence in Europe — uncomfortable for Britain's political class, useful for those who want American troops home.

• Tucker Carlson argues Britain gained nothing from winning the war: the empire collapsed, India was gone within two years, and America took over the world.
• His central claim is that a country hosting foreign soldiers for 80 years cannot call itself sovereign.
• The British side of the argument is that US troops came to hold back Russia and stayed as welcome allies inside NATO.
• The clash turns on what "nation state" even means — shared defense versus independence.

Outlook: Expect more of this sovereignty-versus-NATO argument as the American right keeps pressing Europe to pay for and run its own defense.
