Be sure of your line of fire and know your backstop. Be sure that if you miss your target that you won't hit innocent noncombatants. This is especially true if you suspect that hostages might be involved. If you shoot hostages or bystanders, it is your fault, not your target's. Choose the right weapon for the job.
Air power is insufficient against an entrenched guerilla force defending their home turf.
A cruise missile is overkill if you want to distract people's attention from allegations of rape and molestation, China stealing military technology on your watch, or the contributions that Communist China made to the Clinton-Gore campaign. Keep your gun clean and well-oiled. They are safer that way. Fully fund military hardware maintenance. You are safer that way.
