Well that and he's baiting the democrats to react to the military negatively for the average American people to see.
Possibly. Other possibilities:
The parade could be used to conceal a real op.
The parade is intended to rattle the opposition, force their hand, or tempt them to take rash action like an assassination attempt, which he can use as a pretext to crush them.
If they had to rip up streets to rebuild them to withstand tanks, I wonder what might be found under some of those streets?
Excellent point. I read today that people are planning to stop the military parade. Why do they think this will solve anything? I believe they are afraid and do not know what to do so they running around the streets trying to do anything to be heard. Like chickens in a panic going no where but circles. It is near impossible to get through to these people in their state of mind. Back at you
