Why did it take so long for US troops to enter combat?

The delay in U.S. troops entering combat can be attributed to several factors, including the need for careful planning and logistics, the requirement for political and public support, and the complexities of international relations. Additionally, military strategies often involve extensive preparation and coordination with allies to ensure effective operations. In some instances, there were also attempts to resolve conflicts through diplomacy before resorting to military action. Overall, these considerations contributed to a measured approach before committing troops to combat.
