I think it is true, but since the leaks (I have a feeling Israel is behind it), the pressure that Trump will be facing till next week to water it down will be horrendous. I already saw members of his administration trying to reassure Israel, but it is unequivocal that Trump is having a change of heart, probably since Netanyahu's last visit. Now, like in his previous administration that he ordered the exit Afghanistan and scale down from Syria, the establishment completely disobeyed, dragged their feat or simply followed some one's else orders. Even presidents, with thousands high ranking and autonomous working underneath them, it is very easy to work against the President and even go unnoticed doing so... Once could see this as a safeguard, but it is not in this case.
