If you want a more peaceful and just word, then Democrats aren’t blameless (especially if you give equal value to American and non American lives an alike).
But from a narrow standpoint of what party will start a large scale land war, it was the GOP that started the biggest ground wars fought by Americans in the last 50 years. Meanwhile it was Democrats who withdrew from Iraq and Afghanistan.
I actually could sort of understand this argument in 2016. At that time, Obama was president and Afghanistan was still going on. Moreover, Trump was more of a blank slate. And most worrying of all, Hillary Clinton believed that a politician couldn’t be taken seriously unless they were “tough” on “adversaries.” Although even than, I doubt Hillary Clinton would have committed to a large scale land war.
But in 2024, there’s absolutely no reason to think that war is more likely with Harris as president, rather than Trump. Not only that, but a world of hyper nationalism and economic fragmentation, tend to make very large scale wars much more likely.
Donald Trump is trying to build a world where world war (and the mass mobilization and conscription that comes with it) an inevitability.
If your only interest is NOT being drafted and sent to war, you’re far better off with Harris as president.
