Muslims and Christians have been living in the Holy Land for over a millennia and a half, so the same question can be asked to you from the Muslim or Christian perspective. Why isn't 80% of the Holy Land enough for the Jews? Muslims and Christians have already agreed to take only about 20% of the Holy Land and leave the rest under Jewish rule.
These Zionist Jews are so freaking greedy, that they insist on 100% of the Holy Land, and that will never happen. The West Bank, East Jerusalem, and Gaza belong to both the Muslims and Christians and the rest of the Holy Land belongs to the Jews. It's the "Jewish State". That was agreed upon by Hamas, Fatah, the PA..etc, decades ago. It's the Zionist Jews that insist on taking EVERYTHING, the whole pie for themselves.
Now due to what they have done to Gaza in the last year, leveling the city to the ground, and committing war crimes that amount to genocide, after over a decade of besieging and attacking it, turning it into a giant open-air prison, the Muslims should take it all for themselves. They will defeat the Zionists, it's only a matter of time. Eventually, America under the leadership of the younger, anti-Zionist generation, will defund the Zionist state, ensuring its demise. Again, the only reason this racist, terrorist state exists is thanks to those welfare checks and weapons from Uncle Sam. When they lose that, that's the end of the ZIonist State. Bye bye.
