insurgents or invaders

Why does the media insist on calling the suicide bombers in Iraq insurgents. Insurgents are those within a country in unorganised revolt against their government. While there are some Sunni Iraqis involved in insurgency, the vast majority of jihad suicide martyrs come from other arab lands.They are invaders. These tools of the radical muslim movement have one goal , destroying the fledgling democracy and throwing Iraq into chaos, in hope that an Islamic theocracy will arise. Of course these more moral people would then exercise governing power. As Iran is worse off under theocracy then it was under the shah :Iraq would be worse off under these rulers than it was under Saddam.
