I mean, talk that puts something of hers at stake, theoretically (hardline “we must support israel” voters, which I don’t think really exist in the democratic party, israeli funding, military industrial complex funding, etc.), is talk that is, in and of itself, an action. It could still be a lie, sure, but then it’s a lie that she’s gonna get called out on later and then that’s politically damaging, at least theoretically, especially because it ostracizes her from both the hardline group that wants to support israel and it ostracizes her from the people that actually wanted to do that. Most politicians won’t lie so handily unless they’re real pieces of shit, or unless they think people will just forget. Most politicians will instead try to waffle and weasel and say that oh well I tried to do that guys but it was just too hard! I tried but I couldn’t do it! They try to save face. Taking a hard stance, making a strong commitment, that ensure that you’re sacrificing your ability to save face later on to your voter base, which indicates that you might actually do something.
