The vietcong and Toiletban were able to be resupplied. The cong could cross into Laos, Cambodia. The Toiletban into Pakistan. Hamas has nowhere to run and hide. Egypt current leadership hasn’t forgotten Morsi was in bed with these fuchs. They don’t have any allies willing to air or sealift them stuff. Syria is weak. Lebabon weak. No way Jordan would support them. Iran could prod Hezbollah yo open up the northern front. Israel will destroy whats left of Lebanon and the non shia clans know that. Israel is currently on a good position to destroy hamas. Prob a bit of quick stuff and attrition.
I think you might be underestimating the enemy the last 50 years should perhaps tell you something
it’s never as easy as u think
Unless you dust off the nukes and use them to kill 10s of thousands and demand surrender (like with the Japanese) these wars and conflicts tend to drag on.
This is what the last 50 years has taught us from Korea to Afghanistan.
I dont think nukes will ever be used again so we could be stuck.
