“My goal is to keep the measures ... in place for as short a time as possible and to minimize the impact on outstanding sailors,” Swift and Cloyd wrote.
If these measures are truly effective, then why limit them to a short period of time? Why not implement them everywhere, for that matter?
It's because you have to appear to be "doing something," even if you have no freaking clue what the solution is. If the admiral really thought that scrubbing the "liberty risk" sailors/Marines, and having some TBD sanction placed on them was going to help, he would have had it done already. The new policy is merely so show the Japanese that we mean business.
In the military, we are so inculcated into the "What now, Lieutenant?" mindset, we never consider the fact that sometimes there is no solution, and if there is one, it's one that takes time and patience to succeed, both commodities that are in short supply.
Besides, COA #1 with this policy is to get absolutely shithoused by 2200.
