It's pretty clear that electing the pumpkin twice has dispelled any notions about the US's reliability as a long-term partner. Sure, the next US president will extend a hand in solidarity, but the Europeans can't rely on that happening every 4 years any longer. I think most have figured that out.
The GALILEO decision was in 2006 while George W. Bush was president. Obama would have done the same, it's just a decision that makes sense from a US standpoint.
