How did mcclellan feel the us could win the war?

McClellan was a strategist.  He was called upon in the early days of the war to look far beyond tactics or operations and look at the larger scheme for fighting the was.   He came up with a plan to hammer the Confederacy into submission in one grand campaign.  This campaign included military, diplomatic and political strategies.  His plan asked for simultaneous offensive actions against different parts of the Confederacy and even talked about Mexico helping.  Some of the key parts were clearing Missouri using the troops already there, sending a force of 20000 men, plus those raised in eastern TN and KY down the Mississippi River to seize Nashville and eastern TN along with the state's rail lines and moving from KS to Nebraska against the Red River to take advantage of supposed Union and free state sentiment, and a force of 273000 men would come together for a thrust into Virgina so that they can take over Virgina and move deeper into the south.
