The continuity was in foreign policy. Obama, like GW Bush and Clinton, deferred to the 'Deep State' on foreign policy, military and security matters. He started out idealistic, but was quickly subsumed. Trump has bucked the System, and that is why the bipartisan knives are out for him.
The blob will always be dissatisfied because there is always one more country to invade and one more way to escalate a conflict, and eventually any U.S. politician has to stop giving the blob what it desires if they want to get reelected.
Relative to what Hillary Clinton's or Marco Rubio's foreign policy would have been, sure, Obama was a model of probity, but this is damning with faint praise.
