Well we Europeans are grateful( or should be) the massive cost of NATO was shouldered by the US, and as a result trillions since 1940s, European countries could spend the savings on free health care for all and a decent welfare system.
Trump has put a spanner in the works, Europeans are supposed to increase defense spending to 5% of GDP, the UK currently spends just over 2%, there is no way the UK or other countries can make that target without getting rid of the benefits system.
But the master stroke is the war in Ukraine will continue, but it is the Europeans that will pay for it, Europe does not have the heavy industry to produce weapons in the quantities needed, so they will have to buy the equipment from the US,
sadly for the Russians and Ukrainians they will continue to die, but the rewards for the Industrial and Military complex will be increasing
