I don't think we should be discussion anything. This man and his regime committed the biggest act of mass murder on our soil, let alone the murder of WPC Yvonne Fletcher and the arms sales to the IRA. There is no debate, we have an almost free hand to topple him and his vile family and we should do it.
As for countries like Iran, Syria, Algeria, Venezuela, Cuba, Russia and China complaining. All these nations are run by murdering un democratic despots to a man, and its no wonder that thy don't want to see or even encourage another of their "own" being toppled. We have the chance to crack on and do whats right for the World, and that includes others like Zimbabwe.
The tide for democracy is gathering place all around this region, and we should do everything we can to encourage its progress and pace. Could you really stomach going on your holidays to Malta knowing that just over 100 miles away a regime is murdering its people with air power etc?
