Trump was offered Ukrainian anti-drone systems last year, and he turned it down. There would likely be less destroy American equipment and fewer dead Americans if the US had acquired these systems.
Russians are meeting with Iranians likely to discuss, in part, how to kill American soldiers with drones. Yet, Trump still sings Putin’s praises and insults the country Putin is invading.
Throughout history, even before it became a global superpower, the United States fought to defend the freedom of the seas. If Iran forces the US to accept an extortionary toll on the Strait of Hormuz, it will be a great blow to the US-led order that allows trade across international waters without heavy fees enforced by deadly power.
Control of the Strait gives Iran control over the price of oil. If they want the price higher, they let fewer ships through.
On one hand, Europe isn’t helping the US in the Strait with naval power because of Trump’s atrocious behavior toward Europe. On the other hand, Europe has let their navies so atrophy, that they have no ships to send!
Thanks to Trump repeatedly going back on deals, lying about deals, and pulling out of previous agreements, other countries can’t trust the United States. If a deal requires the US to actually follow through, especially if the other country has to give something first, then that deal is now unlikely because Trump can’t be trusted. This limits the possible deals the US can make.
