Bitcoin Q&A: Governments vs. Proof-of-Work or Proof-of-Stake

If multiple governments collaborated, could they launch a 51% attack on Bitcoin? If all it takes to attack a proof-of-work (PoW) network is enough electricity, wouldn't you want the game theory of delegated proof-of-stake (DPoS), or a hybrid system? Could chainlocks prevent 51% attacks?
