It's pretty simple:
1. Leadership requires clear communication & a single path forward, right or wrong.
2. This is because you can't hit a target you can't see. If success is not defined, then you cannot be successful because you have no targets to hit.
3. A clear plan enables people to get prepared, get to work, pull resources, roll things out, and reduce anxiety.
4. As long as things are a question mark, there's a huge risk for ineffectiveness, because nobody knows exactly what to do & people can't work together effectively to marshal resources properly.
5. You can't always call all of the shots perfectly, but people need something to rally together on. Look at Bush's response to 9/11 - they got us, we're gonna get them, so we went to war with Iraq. Same with Pearl Harbor & going to war with Japan. But you can also see how ineffective things like the Vietnam War were in the minds of Americans because of mushy reasons & mushy plans. Right or wrong, you need a clear path forward defined by leadership.
For reference, America has nearly as many people killed by COVID-19 as South Korea has infected in their
entire country. Their current death count is 186 people, whereas ours is nearly 10,000. Vastly different approach styles:
