Israel has around 170k active soldiers so the idea they will lose 100k (more than half) of those in Gaza and limited skirmishes with Hezbollah is laughable.
Israel has lost at least 1500 lives with c. 10,000+ total casualties. To put this into context, this is the equivalent of the USA suffering 400,000-450,000 total casualties, against a tiny militant group in a tiny blockaded sliver of land while using genocidal scorched earth tactics before entering any area.
For comparison, the US suffered c. 35,000 total casualties between 2003-2010 in Iraq.
Israel is not "winning" this war of attrition by any stretch. It is being bogged down in Gaza with no tangible political results (Hamas fired 20+ rockets into Israel the other day, its domestic weapons manufacturing capabilities still exist, Hamas continue to inflicts dozens of casualties per week, the hostages have not been rescued, and Hamas' top leadership have not been hit) and the north of the Zionist entity has been evacuated for the first time in its history.
