Hijrah is indeed not haram but only logical in this situation if The Great Islamic Alliance would liberate the occuoied territories.
The Great Islamic Alliance can only be established when Turkey, Iran, Egypt and Pakistan forget their rivalries and combine their powers.
Turkey represents the Turkic and the Hanefi states (Azerbaijan, Turkmenistan, Albania, Kosovo, Kazachstan, Uzbekistan, Kirgizia, Bosnia).
Egypt will magnetize the Sunni Arab nations in the Levant and Africa.
Iran will trigger the whole Shia-world.
Pakistan will energize all muslim states in East Asia.
1. Large land troops
2. Massive mechanic infantry
3. Heavy infantry
4. Drones
5. Rocket technology
6. Great Airforce
7. Cyber technology
8. Nukes
These 4 countries have everything except a good economy.
Saudı Arabi, Qatar, Kuwait, Bahrain and UAE can take that part deliver money and oil.
This will trigger a mass effect in the islamic world and volunteers and militias from Algeria, Morocco, Libya, Afghanistan, Indonesia, Azerbaijan, Syria, Iraq, Bosnia, Kosovo, Turkmenistan, Malaysia will join the battle.
The US and the UK are not capable to bomb, invade and annex Turkey, Egypt, Pakistan, Iran, Saudi Arabia, Algeria, Qatar, Mauretania, Bangladesh, UAE, Kuwait, Iraq, Afghanistan, Syria, Jordan, Indonesia, Cameroon, Senegal, Malaysia, Nigeria etc all at the same time. There is no cappacity or social will for that.
Israel will be destroyed and US and UK will be economicly and socially devastated and exhausted.
It will be a total war with great sacrifices and a heavy prize but the only alternative is watch Palestine being history.
