British Inconsistent Promise

The MacMahon-Hussein Correspondence and Balfour Declaration of 1917 are the inconsistent promise British made aiming at settling Israeli-Palestinian conflict. This is said to be a seed of the long-lasting conflict in Palestinian area.

The MacMahon-Hussein Correspondence is the letters exchanged between Husayn Bin Ali and Henry MacMahon, British High Commissioner in Egypt. This correspondence ensured the Arab independence from Ottoman empire and the right to live in Palestinian area.
In contrast, Balfour Declaration of 1917 promised Palestinian area to Jews. The declaration was addressed by Foreign Secretary Arthur James Balfour.

These two are now remembered as a trigger events for the never-ending Israeli-Palestinian conflict.
