My sense at this point is that grotesque flattery works on Trump, but only to a point. Trump doesn't really like anyone, the best you can do is a slightly-better-than-neutral relationship. (And at the other end he's willing to coexist with anyone who hasn't personally slighted him, like Kim Jong Un)
obviously, I doubt Rutte was expecting this message to be shared. If he wasn't a complete moron and actually doing this just to stroke his own ego, I'd actually give Donald props for leaking it, as Rutte kissing Donald's ass makes him look terrible, and more broadly makes the European parts of NATO look terrible.
I imagine Rutte's intent is to stroke Trump's ego to try and keep him interested in NATO, but I feel like that's a fool's errand. Trump doesn't give a shit about anyone else but himself. This new agreement, with NATO signatories needing to commit 5% of their GDP, feels like a grift for the benefit of U.S. defense contractors. The U.S. cannot be trusted to actually honor their agreements anymore, so why pay more into their alliance? Is Europe really that scared of further Russian aggression?
Emperor rutte has spoken. Well deputy emperor to trump, rutte, has spoken. NATO members all agree to destroy their societies in order to boost military spending by 150%. Traitors in member parliaments will need to be executed if they object to the empire.
At least Europes war on Russia will be worth it. Every 100 years, no one left alive to remember last failure.
