text: are we entering a new cold war due to the lack of diplomacy? iran sent president bush a 17 page letter which president bush refused to reply to simply because the letter didn't address issues the way the bush administration would prefer. - this letter to our president was, at least, some dialogue which could have opened a door to further communications between iran and the united states.  north korea, is redirected away from diplomacy with the united states and talks are outsourced to other nations who are supposed to get america's point across.  with out disagreements, there would be little need for diplomacy but without diplomacy, there will never be agreements. yes, and if americans don't find a way to deal with it, violence, and civil war are just around the corner, right here on american soil.
