I always thought Trump missed an important concept with his 'who pays for NATO' rhetoric. A huge amount of NATO spending from Europe was going to US arms companies, so the US benefited massively. Now the US is an unreliable ally, that money will go back into Europe. And even when Trump is gone, governments will still remember that their sovereignty can't depend on the whims of the US. This damage will last a generation. Personally I think this will be an eventual benefit for Europe, who seem quite capable of making advanced weapons when they have to.
Sounds about right.
