1. The IDF will be spread too thin to maintain the intensity of occupations in the West Bank and growing conflict along international borders

2. Their rapidly crumbling international support will take a massive hit from the brutality of such an assault and could prompt direct retaliation from Hezbollah

3. Many, many IDF soldiers will get fucking obliterated entering hyper dense urban combat against a million people with nothing left to lose

These three combine to create the likelihood that Israel would be utterly defeated in such an action. The IDF is a paper tiger when they aren't bombing an imprisoned civilian population.

Thoughts? Am I right or wrong with this take?
