Hamas has had time to fortify their positions, even a few could hold off many attackers.....all their tunnels have been set up with IEDs and are easily defended....sending in a large force sometimes is no better than sending in a medium sized force when it comes to OBUA fighting.Why not airdrop a few thousand members of a Marine strike force or Army rangers with a few dozen Air Cav helos overhead? Add a few A10s. March from one border to the other and stick around while border defenses are fortified by Israelis. Tunnels and enemy ordinance can be found and destroyed. So can the enemy.
We had some scorched earth operations before lighting up Japan. Dresden comes to mind. Putting enough boots on the ground, and I mean thousands, could get it done w/o so many civilian losses. No one wants another Nagasaki or Dresden so why (not) drop a superior force on the ground all at once and get the job done. This idea of simply meeting the enemy with just enough muscle to overcome makes no sense. How many lives have we lost doing just that in Vietnam and the Middle East?
Dozens of Aid trucks have been sitting at the border for days while just a couple miles away people are w/o clean water, medicine and food. And it seems so far that Israeli forces have killed more innocents than Hamas since the 7th.
How can anyone call this ’humanitarian’? This is a war between Israel and Hamas. If Palestinians or Syrians or Iranians help Hamas, they too are the enemy.
Add to this Hamas like all the other terror groups wear the garb of the locals and blend in, it's hard to discern them and even harder to target individuals....(been there got that tee-shirt).
And just like @jellyrug says, it's very hard to tell who is a Hamas fighter and a Palestine citizen as they are often interchangeable much like the Taliban and Afghanis were.....proof of this is evident at all the global protests which are held under the guise of support to Palestine-a people who are led and indoctrinated by Hamas.
