General Discussion

The estimate used during his 1st term was higher. The aircraft and helicopters cost eye watering amounts to fly per hour. Moving them to DC area, servicing, and returning them to active duty while flying empty is enormously wasteful. To say nothing of taking active duty troops out of service to honor a felonious draft dodger who sneers publicly at those same troops for serving our nation.
The structural and surface damage from multiple Abrams tanks driven on city streets not engineered for such loads is not included in the estimates. Neither is the cost of lost public access to those same streets while they are being repaired post parade.

As others have noted Dwight Eisenhower said there was no purpose or need for America to put on such a parade imitating lawless tyrants elsewhere. We are the most powerful country in the world. Such a parade mocks those who serve our nation as citizen soldiers and offends America's heritage as a democracy rather than a military state.
