We agree on Tariffs.historian said:
The U.S. has the largest economy in human history since 1900. We most definitely were an economic world power at the time but not militarily and not so much politically because we chose not to use our international political power very much. WWI changed things a little since the US was the decisive factor in the allied victory even though we were not a filly ally in the legal sense (no treaty). It didn't really change until the end of WWII.
Moving to tariff only is unrealistic for multiple reasons. The world is so different than it was 100 years ago it's ridiculous to think we could go back. It's not in our interest to pull back that radically from world affairs. We must remain involved to some extent. That does not mean we need to have military forces in 100+ countries, fight ridiculous & costly "forever wars", or give billions to countries like Ukraine to maintain such a war. Domestically, we probably do need a drastic curtailment but will almost certainly not happen. That's where the budget will be brought under control and the economy turned back towards long term prosperity.
The budget must be balanced and the debt reduced. That is an imperative.
I am all for not fighting forever wars. But, I do want the US to have a presence in the 100+ Nations. Special Operations does an excellent job of providing the presence with advisors and task forces there for a specific purpose. I think Africa is a prime example of a model, at least I like it, that works and is cost efficient.
For example, of some military spending that I think show the potential value of DOD, besides basic defense and war fighting.
The Anti-Piracy Task Force in the Horn of Africa. There for a specific purpose that supports freedom of navigation. Multi-National and provides benefit as well as presence. Think it is an example of the US Military at its best modern use.
Advisors, specially trained to provide and teach how the US military operates and force multipliers. Worth the money invested.
USAF Pararescue - Premier Paramedics in the world, they serve a purpose under any conditions. See the Earthquakes in Northern Calf those guys went underground to rescue people. A story that did not get enough press.
Freedom of Navigation - This is what our Destroyers were made to accomplish. I support this fully.
Anti-Terror Units - Not massive deployments, but targeted protection. Would like to see more on Border.
I am sure there are more, just the ones that I see.
