"there is little evidence that the Bush Administration and Congressional Republicans have a coherent strategy to stabilize Iraq."
While the letter, which you can read here,
http://www.housedemocrats.gov/news/librarydetail.cfm?library_content_id=842, is at least a unified message from every ranking Democrat on virtually every House and Senate committee, it has its share of tribulations.
The dilemma is, writing letters to a man (Bush) who publicly admits he does NOT read, is unlikely to produce meaningful results. Further, asking Bush to "please withdraw the troops because we asked nicely", is analogous to sending a letter to the neighborhood bully and pleading for your ball back or to not get beat up again! It is extremely likely to fall on deaf ears and meet the circular file in a rapid fashion!
I must also point out that even revolutionary words (which these were certainly not), no matter how eloquently spoken, accomplish little by themselves. Galvanizing words coupled with assertive action -- to right that which is wrong -- is the only avenue that will truly affect change. Words absent subsequent actions are merely futile rhetoric.
While I applaud the Democratic leadership for finally bringing forth a cohesive message condemning the illegal and groundless act of aggression against Iraq after three years, I wonder how long it will be, or how many more people will die, before a unified cry of impeachment will echo in the halls of the Democratic Congress? Don't hold your breath.
If you ask Nancy Pelosi, House Minority Leader for the Democrats, the answer would be, "Never!" I presume that Nancy and her posse will keep on writing "Dear Mr. President Letters" and more soldiers and Iraqis will continue to die for the foreseeable future.
In this case, the pen is truly not mightier than the sword.
