To apportion forces appropriately, the relevant Combatant Commanders based their contingency planning on the assumption that the two concurrent MTWs would develop sequentially.

The shift in focus on the two MTWs was a method for breaking away from the Cold War paradigm, but in a cautious and sensible manner that did not reject the possibility of significant conventional conflict.
