I can say with a fair degree of confidence that most guerilla forces 'win' by merely surviving.
In case of Israel, the mere survival of Hezbollah, the Palestinians in the West Bank and Gaza is a huge strategic problem. Why so? Because another October 7 can be repeated and thanks to the cursed Israeli geography and it's relative unwillingless to take a lot of casualties, even October 7 like events become 'strategic' in nature. You know what: Israelis are already terrified of some 'digging' going on it the West Bank in fear of another October 7??
In contrast, countries like India and Pakistan have seen a lot internal violence/terrorism since the early 1990s but they can 'absorb' such violence due to the large population, large land area, and indeed due to the ability to 'take it on the chin' attitude. All Indians and Pakistanis know that!!!
