Israel states they wish to eliminate Hamas. I understand and respect a country that wishes to exterminate a bunch or terrorists that has murdered a number of its citizens. My question is how this could realistically be done in Gaza?

When Israel sends troops into Gaza, who are they targeting? Do they know exactly which men raided Israel and where they are located? Do they know who in Gaza helped support them?

Are they aware of certain buildings where Hamas operations are run out of and targeting those?

Or are they just marching\driving through the streets and and waiting for someone to shoot at them so they can fire back?

It seems to me, that elimination of Hamas would be almost impossible as it is an idea more than it is some specific people. It would be like trying to kill all of MAGA.

Maybe I'm wrong. I'm just wishing to hear from anyone that has better understanding on this than I have.
