No invasion (yet). Just bombing.
This is not a useful delineation for what constitutes a military invasion. Invasion means landing troops and controlling territory.
Based on what we're being told now, this was an extraction. (Slash detention. Slash kidnapping. In any case, requiring troop transport and extraction.)
Seriously, I'm patiently waiting for the day America or Russia will do the same to Netanyahu, who is an actual war criminal. Not holding my breath.
