Remind me , what happened between 88 and now , that somehow made pre-emptive strikes , punitive raids , and general invasions of foreign nations ilegal ? Nada , zip , nothing.The only thing that will be different is the pretext for the action.
This is the real world , if a serving president deems a foreign nation a threat to the US , it will be dealt with regardless of right or wrong, if that means sanctions fine, if it means a raid , fine , if it means invasion and regime change , then so be it.
After 911 are you seriously going to ask if they have that right ?
As for Iraq , it sorta brings home the argument. In the first case Iran stopped em cold , and then slugged it out with them to an 8 year stalemate. In the second , Iraq invaded Kuwait and then was kicked out by allied forces in the subsequent desert storm.
In both cases they had that right , according to surprise surprise , themselves. In the first case , the world could care less if they bashed each other about , it was only when they started involving others in the tanker war ,that others bashed back , with praying mantis. In the second , Iraq deemed that the world would not care ,and thus invaded, they were kicked out but it took a stronger power to do it.
Until that stronger power comes along , the US has the right , not only to invade someone , but to get away with it as well, if you believe its ilegal.
