Per news reports, Israel has allowed Qatar to give hundreds of millions of dollars in aid through Hamas. Hamas has collected revenue for years by taxing goods that moved through its tunnels and through the Salah al-Din border crossing. Hamas has reportedly accumulated over $12 million per month from taxes on goods imported from Egypt into Gaza as of 2021. Iran provides some $100 million annually to Hamas and other Palestinian groups.

What did Hamas do with all this money? Did they improve the lives of the people living there? No. they build a war machine three levels underground.

The Palestinians are arabs who happen to have been located in that area of the region. The "Palestinian People" is actually an invention in 1967
