This is the first time that US troops have been killed by enemy fire in the Middle East since the beginning of the war in Gaza.
What is clear now is that these attacks are not only increasing but settling into a new type of routine.
India's navy deployed three destroyers to maintain a deterrent presence in various locations after an attack near India's waters.
For Austin, the trip is a delicate balancing act.
US CENTCOM said that four attacks had been conducted against three separate commercial vessels in the southern Red Sea.
The strikes targeted a training facility and a safe house near the cities of al-Bukamal and al-Mayadeen.
Shortly after the strike, Iran-backed militias targeted three US bases in Syria and Iraq.
The US also seeks to deter Iran. Iran has backed proxies in Iraq and Syria to attack US forces.
Iran released a video that looked like the US heeded its threats, but was it real?
There is no shortage of US Air Force assets and other weapons within the CENTCOM area. However, the decision to keep releasing details on these deployments is clear messaging to Iran and Russia.
