-——”there is “no such obligation” not to target Hamas leaders abroad”——
When Hamas is destroyed in Gaza and on the West Bank, the leaders in Qatar no longer have followers and cease to be leaders.
And when there are no more hostages, they no longer have any leverage whatsoever. At that point, the Qataris may hand them over in a box, with rapping and a bowed ribbon, and thank us for respecting their sovereignty.
