We could say the same about US citizens and Biden. Or Trump. Or Obama. Or Bush. Or Afghanistan. Or 9/11. Or the Patriot Act.
Democracies are funny things.
1. They claim to have charge of their government
2. They fail to control their government
3. Their government sends out military adventurism at behest of niche economic interests and draws foreign ire for doing so
4. Yet somehow the democracy thinks it is immune from retaliation (i.e. "That's Terrorism and you can't do that!") for the actions of its government that it failed to control
At a certain threshold, it is most certainly legitimate to target the populace for supporting its government in warfare.
