I understand your reasons- Trump definitely seemed a safer choice in this respect. However, that probably shows that it's not enough to say you have an opinion or a stance on something; you can only be trusted to keep it if you are already aware, at the moment of expressing it, of all the arguments and forces that will push you in another direction. Three months (of undoubtedly powerful lobbying) have been enough to sway Trump from "no more wars" to "yes let's start another one, possibly with Russia".
