The funny thing about that is you can frame lots of things that way.

For example, "if China were secretly conspiring to sabotage the US, they would goad the US into a war with Iran".

Anyway, as far as Europe's self-sabotage goes, I don't think China has much to do with it. The US however does. Trump browbeating NATO countries to spend 5% of GDP on defense is both a gift to US weapons manufacturers and a foil to dismantle the social welfare states in Europe. Because of different versions of austerity, those defense dollars come directly at the expensive of the social safety net and the tenets of European social democracy. I really don't think that's an accident either.

It's also true that Europe has been asleep at the wheel, perfectly happy to outsource their defense to the US. I am skeptical that the political will exists to replace foreign military hardware with homegrown industries but I believe that Europe needs to be responsible for its own security if it's to survive long term.
