much valued highly-incomparable antiquary has been pilfered from Egypt-why has Egypt allowed such GREAT theft?

while wondering through London's British museum - i noticed that much incredible-irreplaceable antiquary - having belonged to the great pharaohs of 6000-6500 years ago, was on display.

the person who had accompanied me, told me - that the British had simply taken this priceless loot.

if this is true - what was Egypt doing while this disrespectful looting was taking place???

does anyone know the true history to this???

thank you.
