I think reasonable people can disagree about this. Trump is pretty good with the "flimsy excuse", like "look I said 'stand back' as well as 'stand by'" or "hey I said 'peacefully and patriotically'". Probably whether you're willing to give him the benefit of the doubt on these kinds of things is some kind of political ink blot test, but to me, he definitely has the instinct and pattern of "say it without saying it".

Most leaders are aware that people might cue off of what they're saying and do something very bad, so they stay far away from rhetoric like this. Trump (deliberately IMO) does the opposite for political gain. So even if I agree this is about combat, what's the difference? He's once again engaging in his pattern of dehumanizing his opponents and advocating violence against them, which has led to actual violence.

Elsewhere you pointed out this is pretty similar to Vietnam War protests. I think generally that's right (again "Fortunate Son"), but there are some differences. First is there isn't a draft; we have an all volunteer force (though there's a big discussion to be had about economic exploitation and multi-generational military families). Second, she wasn't even in Congress during Bush 2 and AFAIK had no policy making power where she was at State.

Do I love Liz Cheney? Hell no; her policy positions are one disaster after the next. I believe she should be vigorously opposed in every election she runs in. But do I think she should be subject to wink wink "sure would be a shame if something happened to Liz Cheney" rhetoric from maybe the most powerful person on Earth? Absolutely not; no one deserves that.
