"so called missile shield is nothing more than just a money pit."
False statement.
"It is not protecting our interests and it is pissing Russia off for no good reason."
Since it does protect our interests, I could care less if Russia is pissed off.
"Let Europe defend themselves if they think they need such defense."
We have treaty obligations that would cause us ( Under MAD, which seems so highly thought of) to destroy the world if any nuclear missiles hit our allies.
"It would totally defy logic and common sense to think that Iran would lob nuclear tipped missiles at Europe."
Totally unproven statement.
"For one thing. They don't have any."
False statement- we don't KNOW if they have the warheads, they do have the fissionable material to build them, and the DO have the missiles already in operation- DIdn't youy notice that had launched a satellite?
"For two, it would serve them no strategic purpose "
So, anything that does not serve strategic purpose will not happen? I claim that the Iranians have a percieved strategic purpose.
"and for three it would lead to the total and immediate destruction of their government and military."
Not if they don't think we would respond to a missile launched with "plausible deniability"- ie, by some non-government group such as the Guard ( You know, the ones who kidnapped the British navy personnel)
"You don't really think that Iran's leaders are braver than the Neocons do you? The Neocons are afraid of the political fallout from using WMD. The fallout the Iranian's fear would be much more concrete. "
Bravery has nothing to do with it- IF the PERCEPTION is that they can get away with it, the possibility exists they will try it, and we would be idiots to NOT try to be prepared for the situation. Unless you want us to invade Iran, in order to keep them from ( finishing) the development of WMD?????
