Picking a fight with a superpower is generally a poor idea. Killing military members - even in Jordan - might be considered a bit beyond mere commerce.

Edit: I did misremember the attackers in Jordan and thought that was part of the Houthi organization. The Houthi's are attacking US warship(s) in the area, but haven't directly killed an US service members that we know of/yet. The Jordan attack was (now that I've checked again) by one of the groups operating under the Islamic Resistance in Iraq.

My only defense here is that all of these attacks on US and UK vessels (merchant and military) are in retribution for the US support of Israel. And, yes, there are a lot of groups backed by Iran and Iraq who are using the Israel-Hamas/Israel destruction of Gaza as an excuse to lash out at Western powers who (generally) provide support to Israel. My apologies for the error.
