Arabs owe nothing to Turks correct , Turks brought nothing except poverty and misery to the Arab world.
There is no difference between Othman or British colonization , the only difference was that Turks used religion to justify their rule , just like how Roman Catholic church justified ruling over most of Europe.
Arabian peninsula was only developed after Arabs kicked Turkish occupiers out , as for Palestine the Turks sold it to the Jews before WW1 , Jewish colonization started in 1800s .
Othmans were already weak at that time and gave up alot of Muslim held territory to Russia such as caucus , circassia and central Asia .
