You might very well encourage uprisings without putting boots on the ground. US government does it quite often.
Venezuela is a recent example. US called for the uprising and supported it and some probably expected US troops to back the protests.
Is it a warcrime that the troops didn’t follow?
Run that scenario by me *after* we put the 101st Airborne on the border, wait until the Venezuelans bleed themselves dry in armed conflict trying to overthrow the current regime, and then once they clear the dead bodies out of Caracas we march on through to take on drug lords in Columbia.
