Why the uS and UK are right to offer Assad exile from Syria,

1) His country is according to UK news channels at risk of civil war and teh Un monitors are fiding it hard to do their job.
2) A peace plan which allows for fresh elections is better than a coup which if it went wrong in the 'trainsition phase' could risk their military becoming sectarian and carrying on the attrocities or launch a war on Israel over teh Golan rather than the next elected Syrian government seeking negotiations ove r teh territory and regional intergovernmental negotiation over the share of water utilities.
3) On a personal note as a member of a Syrian minority himself he and his family could be targetted.
4) At a later date he could be arrested if indited specifically by a vote at teh United Nations to stand trial while in a safe country rather than being killed like the late Colonel Gadaffi

Greece needs stabilty' to quote teh spoliticians post election result.

Heres why:

1) All Euro countries are linked in the Euro in terms of their debt
2) For one to write off an unagreed amount could destabilise the eocnomy in all the others, leading to teh collapse of teh Euro or large inflation rates as occurred in China and India and the United States in previous economic situations of an equal or lesser scale
3) This could risk the reelection of hard / far left and right parties as in the 1930s
4) The unmanaged default could affect the developing world who are dependent on aid and risk arms races rather than cooperation on civilian fuel provision for nuclear weapons which to date Iran has been complying with. However there is a risk that sanctions rather than global nuclear disarmament could make them develop nuke missiles at an IAEA unregulated location

Hence as the G20 / B20 meet perhaps its time to consider the need for global nulcear disarmament, the recall of all battlefield WMDs (such as radiological tipped ammunition and deplted uranium shells), IAEA ownership and regulation of all civilian nuclear fuel plants globally and managed sovereign debt restructuring or default so as to stabilise investment in energy and technology such as the issue of clearing space debris which after 51 years of earth sattellites, can pose as much a risk in the future as the rogue asteroid hitting the planet

Also Greece needs stable trade and bilateral relations with Turkey at this time so as to prevent arms proliferation and aid peace over Cyprus to adi co-ordinated aid to Syria under clear international guidance and where agreed UN peacekeeping
