Libya no fly zone.

I see on the news today the the USA and UK governments are calling on the UN to impose a no fly zone on Libya.
Col Gaddafi's forces have been bombing rebel held areas and the US/UK want it stopped... Which is a bit odd considering.
A. The UN states that countries shouldn't interfere in the internal workings of another country.
B. How fond the US and UK are of bombing rebels in other peoples countries, like Iraq, Afghanistan, Bosnia, Vietnam, Yemen, Somaila, Pakistan, Yugoslavia, Sudan, etc etc.
Talk about double standard.
