I do not know.
This is obsurd, all nations try to safeguard their interests and allies. Now find a quote where i said otherwise. The issue here is your fanboy statment about 'chest thumping'. Russia sent ships to Syria to insure its intrests. You may interpret that as chest thumping but i'm sure that Russia put alot of though into sending Russian ships into Syria. If Russia wanted to thump its chest it would just do what NATO does by bombing peasent countries.
No one is mentioning any constitutions, so once again, if groups of armed individuals tried to overthrow the Australian government do you beleive that the Australians would sit back and do nothing. There is a reason that all forign leaders are carefuly protected by internal security as well as military; and to internal security or military it does not matter if the threat is forign or demestic, if the president is in any danger they will shoot to kill. Hit, hint just like what is happening in Syria.
And people that try to overthrow governments could care less about the constitutions, the constitutions are like toilet paper to them. So once agin, do you beleive that Syria should let armed criminals kill its military personal and take power?
So your idea of democracy is to bomb other countries or try to topple governments by force. If you feel that way go pick up a gun and storm the Australian parliament if you don't have the guts than surly you won't subject if someone else does, afterall you seems to support what is happening in Syria.
