ELI5: Why is the US legally allowed to fly drones in foreign airspaces and kill terror suspects?

Aren't they violating other nations' airspaces? Also, why do these nations allow their citizens to be bombed and killed by a foreign nation without a trial?

"Legal" has very little meaning in international politics on this level. What matters is, "Who is going to complain?" and "What are they going to do about it?". When possible, the USA gets either official or de-facto cooperation from the state in question and if that state doesn't complain with diplomatic force, then nothing comes of it (e.g. Pakistan and Yemen). In other cases, the USA puts great diplomatic effort into ensuring that no complaints are going to shake the support or indifference of its allies (e.g. Libya and Syria).
