The only reason they can afford socialism in Europe.
Is because the US has been footing the bill for their defense since WW II ended.
The UK, Ireland, France, Germany, Italy, Spain, and the rest of them with almost non-existent military would have been buried under a mountain of debt decades ago if they had to pay for their social welfare states and their own national defense.
As is their welfare/nanny state policies are still crushing them, even with US defense subsidies.
