It might be said that the internal resistance to Donald Trump's orders and measures could force him to reconsider and back down. The Trump administration wants Saudi Arabia to take a proactive role in stopping terror financing, not necessarily in an overt manner. The Trump administration intends to strictly enforce the nuclear agreement with Iran rather than run it through the paper shredder. In other words, the thinking in the Trump administration is that Obama had pursued an unrealistic policy, while Trump is looking to "change declared policy to match reality." Anything and everything is possible in the time of unconventional surprises promised by Trump, and unconventional alliances being drafted by Trump and Putin.
