"Another War for USA?"
No. That's very much out of the question.
"Another 9/11"
I don't really know what you mean.
"Another Bush?"
This isn't particularly relevant to the Oil issue, but I'll say 'probably not' to that, too. The US can only take so much Bush.
What will be the option this time? Whoever gets presidency...will make the fate of USA, Crash or Avoid Crash is the question, because I doubt anyone will come out with a cheap reliable answer, unless that person reforms whole budget system of USA, Mike Gravel? Myro's beloved Ron Paul?
Mike Gravel is a footnote; Ron Paul's solution would involve the implicit assumption that the people will do something as the government steps away from regulating it. Neither are relevant much to the issue at hand here.
The budget system of the USA does not need a complete overhaul as you suggest (well, at least this certainly doesn't follow from high oil prices). The budget itself, perhaps, but the system, flawed as it is, works well enough in theory to accommodate changes. The next Democratic presidency will likely be under massive pressure from the people and interest groups to undo the damage of the Bush presidency (see Bush EPA). This at the very least would warrant greater research into alternative fuels, more environment spending, and whatnot.
None of this will help much. Developing viable alternatives will take longer time than we really have. Gas will become quite expensive in the twilight of America's energy crisis, such is life, we will complain and deal with it. My apologies for speaking in such ambivalent generality, but I simply don't see too much remarkable to say about the issue - it is an issue, it will be addressed as public pressure dictates, it will cause problems, it will be solved.... slowly, and in patchwork. I suppose that's the American way.
