...it may not let NATO use its territory to supply troops in Afghanistan if the alliance doesn't seriously consider its objections to a U.S.-led missile shield for Europe...No problem -- we may start using Turkish bases to supply the Chechens and other Muzzie independence movements. Problem solved. Oh, and still build and deploy the missiles shield. Those a-holes had a chance (more than one) to agree to Reagan's proposals in the 1980s, now they'll have to live with the consequences of their own stupidity.
Well, disallowing one to use its territory to supply troops somewhere and starting to supply terrorists are not the things of the same kind.
In fact it is a sovereign right of every nation to decide if they are allowing foreign military transit or not and most nations are disallowing by default which can’t be considered as a hostile act under any law.
Supporting jihadi terrorists is an illegal act in its nature and contradicts all the American interests as well.
