As long as the weapons are destroyed AFTER Syria takes formal delivery then its not a problem for the west if we try and attack the convoy whilst the weapons are still in Russian hands then thats declaring war against Russia and the US will not be to happy about trying to break up a declaration of war against Russia. So if anything is done it will be after Assad has taken delivery but probably before his people have learned how to use it. It is time though for Obama to stop pretending there is a dipomatic solution which there is not and if military action is not taken soon Assads defenses will be to strong for any kind of no fly zone to take place and there may be American casualties if they decide to attack. Obama sat around playing diplomatic games with Iran for the past 5 years nearly and during that time they have increased their defensive and offensive capabilities as well as enriching uranium and so now the US is the only one who can stop Iran Israel doesn't have the capability now and an arial campaign carried out by the US would be much harder than it would have been if Obama was not playing diplomatic games and going round and round in a circle getting nowhere. Keep playing diplomacy with Syria and soon enough only the US will be able to do the job forcing them to do all the dirty work and making the job for them as well much harder. Give Israel the ok and any special weapons that might be needed and we will do the job and I imagine if Israel starts the other regional power Turkey will also join the action so pretty soon all Assads defenses and many of his offensive weapons will be out of action allowing the US to deal with the WMDS if they want to or allow the British and French to operate a no fly zone without fear of their jets being downed.
