Doctors don't have sworn enemies, they have patients.

Any doctor in any country is under obligation to treat anyone who presents if they are in a position to do so in an emergency and cannot refuse treatment electively on the basis of enemy.

It's called The Hippocratic Oath and forms the basis of the moral obligations of registration. Benevolence has nothing to do with it. It is a professional obligation.

A Palestinian doctor treats Israelis and vice versa. Both The UK and USA recognise medical schools in the area so on that alone, my knowledge serves me.

Poo Bad, is your comment about sworn enemy from ignorance or maliciousness?

Tell you what, is this lack of knowledge feeding all your other comments or is it healthcare you have no idea of?
