Eh, I guess I'll just offer my $0.02 to this...
1. Is the right to bear arms in the US more important than dealing with the social problems giving rise to the fear that causes citizens to bear those arms?
I think *some* of the motives for the continuing push to bear arms are rooted in the attempt to preserve civil liberties. There is already a dilemma where people feel they need guns. The situation isn't really getting better by making it increasingly difficult and punitive to own/use/defend with a gun. I agree - there are lots of social issues in the U.S. that should be addressed. There are groups who support many programs aimed at allowing people to find alternatives to violence.
Unfortunately, the majority of gun violence remains segregated. I'd like to see a breakdown of gun murder victims and convicted "triggerpersons" to see if there is a clear socioeconomic divergence. From what I've seen - there definintely is a sub-group of US citizens who continue to commit gun violence. Mr. and Mrs. Smith who bakes cookies for the local church out of her $350K home with her 2 kids in prep school is much much much less likely to blow your head off with a gun than Mr. Smith who dropped out of high school and has been a small time dealer for 2 years.
America has some severe issues with poverty that can't be "fixed" easily. Just because some high-profile people push the gun issue does not mean the other problems are being ignored.
2. The US builds and uses bigger, better and smarter weapons to wage war against nations. Does it develop an equal amount of policy and strategy to bridge the differences between it and nations?
Why the heck would you need all these fancy munitions if not to be extremely superior to your would-be enemies? Geeez man - wtf?
Many of the new weapons are being developed because it is known that the "people" don't want to fight wars. But, they don't really mind being involved with one if they think they'll win. Sooooo, if you have robots and crazy warheads killing for you - no more worries.
I highly doubt that many people in this world feel very safe and secure. The weapons development is just another indicator that there are many scared people out there.
3. The US has thousands of nuclear arms. Why?
Read #2. Hey - don't forget about Isreal, Pakistan, North Korea, and Russia (well, sorta).
4. "If you are not with us you are against us." Is that true?
You ought to just sit there quitely in the corner instead of asking all these questions
