Don't you ever get tired of looking stupid?
Stupid is, as stupid does. Where have I heard that before?
First off, let me thank you for providing your sources. Most people can't even do that.
With that being said, let's get started...
In reference to this link...
...it only "claims" they are a state sponsor of terror, then it admits these are only "accusations".
Iran has long been an active sponsor of Islamic terrorism, including accusations of it supporting subversive activities in Iraq.
You do realize, accusations is not proof?
In reference to the next link...
...it provides this little tidbit...
Former U.S. Director of National Intelligence Michael McConnell told CFR.org in June 2007 there is "overwhelming evidence" that Iran supports terrorists in Iraq and "compelling" evidence that it does the same in Afghanistan.
...of which, the "overwhelming evidence" takes you to another link that says this...
Admiral Michael McConnell, the U.S. director of national intelligence, says there is “overwhelming evidence” that Tehran is supporting insurgents in Iraq and “compelling” evidence that the same is happening in Afghanistan. McConnell cites insurgents’ increasing use of effective roadside bombs known as Explosively Formed Projectiles that are clearly traceable to Iran.
...which just re-states what he said in your link and then added another claim that these bombs were traceable back to Iran. The problem with that is, people defending their homeland from foreign invaders, are not terrorists. In this case, Iran could arm them to the teeth and it still wouldn't be supporting terrorists. Because every citizen, in every country, has the right to defend themselves from foreign aggression.
Or do you think that American exceptionalism also means any country we invade, we automatically become the indigenous population?
As far as this link...
...it's a fucking joke! They just make the same dogmatic claim, but do not list anything specific to back that up.
As far as this link...
...who gives a shit what Israel dismisses! What Iran does within their own sovereign borders, is none of Israel's god-damn business. That is between Iran and the UN.
I know, here's a trade-off, how about Iran opening up all of their nuclear sites for inspection, as long as Israel does the same? Deal?
