[Call of Duty] Why did a traditional ground war occur in Modern Warfare 2 and 3 instead of nuclear warfare?

Title. I'm confused as to why they didn't nuke America, or why America didn't nuke Russia when they invaded the US, or why they didn't nuke the Russian fleet attacking New York, etc.

Same reason you don't use a flamethrower to kill the weeds in your yard. Dropping a nuke is for the absolute last resort where defeat is the only option left to you so you decide to take everyone else with you. Using a nuke on a fleet or on home soil is not only inviting retaliation from the opposite country in the form of nuclear annihilation but also destroying anything you or your people could possibly use. Even if you nuke dc it'd be decades before you could safely return to it after somehow surviving the war. And a nuke at sea will poison the ocean for decades killing off untold millions of fish and marine life causing an ecological and economic collapse of anyone depending on those waters.
