The Israelis cannot provide the Palestinians in the West Bank and Gaza with the good life, because along with it they would have to provide citizenship. Ever wonder why they annexed the Golan Heights, tried to force down the throats of the Arab Druze the idea of Israeli citizenship but never did the same to the West Bank and Gaza. Because it would mean the end of the "Jewish state". The Han Chinese never have to worry about this problem, in fact its the other way around with them assimilating the Tibetans.
Not so sure all of the Druze in Golan Heights are "forced down" the throats to obtain Israeli citizenship. Unlike the Kurds, I could not recall Druze in Lebanon, Syria & Israel all share the same wave length to have a country (Druzstan??) of their own. Many if not all of them are loyal to the host countries and dare to say they live peacefully with Jews way more often than either Shia or Sunni Arabs in Lebanon or Syria.
Plus many of their men are volunteered
and accepted to be part of the IDF, almost on equal terms to service in all branches except Sayerot & IAF. Tell this to the Palestinian Arabs, Christians (not the Lebanese who once served in SLA before 2000) in particular living in Israel. Everybody in Israel knows unless you are part of Hasidim or just making an aliya, moving ahead in the society will be a big handicap for men who do not serve IDF for 3 years.
The only drawback one could recall would be during 1982 invasion in Lebanon, the Druze battalions and commandos declined to fight in the battlefields known to be populated with their cousins, while they had no problems to fight the PLOs and even the Amal guerrillas, junior brother of the Hizbullahs as Israel's supposedly ally Christian Phlangists stood by, doing nothing.
As far as the Han Chinese in Tibet and Xinjiang are concerns, I suspect you really mean it is the Tibetans who have fears to be assimilated, pretty much like what ends up to the Manchus, Inner Mongolians and in a way Korean minorities in China.
BTW, Dalai Lama knows too well this inevitable outcome, especially after Chinese invested Billions of USD to build the infrastructures and modernize Tibet, for better or for worse. All he really wants from China is cultural autonomy, not outright independence since Tibet is in no shape to stand on their own feet, other than becoming India proxy state like Nepal or Bhutan.
Still, the Han Chinese, PLA and People's Armed Police in particular need to pick up lessons and absorb all knowledge fast from their West Bank/Golan Heights settlers, IDF and Magav counterparts to prepare themselves from possible violent backlash globally, including Canada. Dalai Lama and those around him are disturbingly becoming Arafat/Mahmoud Abbas, aka Abu Mazan and the Fatah after Oslo, while the new generation of Tibetan Exiles both in India and the west are becoming radical. Many are becoming militants like their counterparts in Hamas and Islamic Jihads and they probably believe the alternative to this "stalemate/deadlock" would be terrorism, convincing themselves that this is the only language the Han Chinese could understand.
Beijing is making a huge mistake to undermine Dalai Lama while he's still healthy and literally giving the militants in the exile camp ammunition to question Dalai Lama's legitimacy, maybe even overthrowing his exile government when he's incapable to run due to illness. Allowing the situation to degenerate like this would create risks for the Chinese in the proper and their overseas breathen (100% or mixed heritage), making them very vulnerable to reprisal and terrorists attacks. It would not be a surprise should these attacks happen, the western countries would turn a blind eye most of the time in order to cave in the "bleeding heart" constituents, while China is caught unprepared and incapable to protect their people and retaliate with superb and flawless executions like the Israelis most of the time.
