I'm not going to shout treason, because it is your right to write and sign this letter even though it weaken the United States and inflames conflict. I am going to say that writing this letter is ghastly short-sighted. Diplomatic negotiations cannot please everyone, let alone people that don't even come to the table. To demand that half of the United States Senate be given more consideration than five nations, the Iran government, and the executive branch is beyond insane. If you want something to come out of negotiations, then try to achieve that through negotiations. If you want to attack Iran, control Iran, control the world.... then your sense of power and your sense of what is right is out of proportion. If you think that talking will never work, then of course war will always result. That's what happens when you settle your differences without talking. There is no reason for you to undermine another's attempt, let alone the attempts of seven major powers because of your own views. This is bigger than you, believe it or not. Fortunately, you do have your own power, so when the results of negotiations are brought to the Senate, you can then try to work out your own version of how you and the rest of the world can mange to coexist. If you keep wanting to threaten and control the rest of the world as you see fit, it may not even harm you now.... but eventually our future will be swallowed up by the results of endless reliance on fear, force and noncooperation. Death, debt, enmity, estrangement, stagnation, fear, instability, and weakness. Because, yes, building is hard and slow to yield benefit, and hope is so much less appealing than fear. But that is the world I want to live in. Kindly let people with different views than yours continue to work toward their futures even when you don't agree with it completely. It's an important part of being civilized and living in a world full of people with different views.
