Kerry vs Bush on national security

[2VP]

Now please take into account before answering that I'm not from the States.
In today's uncertain environment does it really matter who runs the show in regards to terrorism. What I mean by that is if Kerry is elected wouldn't he be shown everything that the States and the allies have in regards to the problems we are facing and basically say "holy crap" Bush was right we need to get medieval on their asses with or without public or international support?

I ask this because there seems to be a lot of support for Bush here despite what CNN and the like report about Kerry being favorite among the serving members do to his prior service and the apparent lack of Bush's.

I also haven't read the plethora of posts and I'm still very green here.
