Easiest way to really get a nuke in MW2?

I would run cold blooded. Use the weapon of you choice (what your good with) and IMO the kill streaks should be harrier strike, chopper gunner and nuke. if you can get to seven kills (harrier strike) and find a good hiding spot the harrier strike and chopper gunner should take care of the rest. Every time I've got a nuke the most kills I would have to get after the chopper gunner is maybe 1. I've had a lot of nukes. Ground war is usually the best game mode because there are more targets to shoot at.
