Hmmm, wow. . I did have the fortitude to read it all, but I'm not sure I can respond to it all.
I'll just say one brief thing, that no doubt a lot of the perception that Democrats are "weak" on national security is
1- A myth created by by the right. One of their biggest issues which they repeat all the time is how Clinton "gutted" the military. They never mention how military spending kept falling throughout all of George Bush Sr.'s term, and that the end of the Cold War combined with an even worse budget situation thatn we have today more than anything else contributed to the closing of a lot of bases. Another charge they keep repeating is how Clinton did "nothing" against terrorists. This is both untrue and reflects an unfair projection of post-9/11 mentality onto pre-9/11 situations. Clinton responded to every single terrorist attack that happened on his watch and gave far more money and attention to terrorism than any previous president. The Egyptian mastermind of the 1993 WTC attack which Clinton supposedly "ignored" was arrested within two years. You never hear Reagan getting chewed out for pulling out of Lebanon after the Marine barracks bombings.
2- An almost unavoidable aspect to opposition of the war in Iraq. "Opposing the war yet supporting the troops" is one of those difficult nuanced positions you're talking about.
Support the troops - bring them home to safety.
