That bit I emphasized made me chuckle. The P-8 Poseidon is 737-sized because it's derived from the 737. This is not unusual for US military aircraft. Boeing already has the ability to build 737s, modifying one to meet particular mission needs is much cheaper than doing a total redesign and custom build (it will still be heavily modified, of course).
There's no "worthiness", no "honor" in war. There's just dumb young men being sent to kill, rape, and die by evil old men.
The only exception is if you're fighting purely in defense of your country. But that's not what any of these so called "honorable, worthy" opponents were doing.
Both pale in comparison to the amount of precision-guided weaponry that was burned through blowing up fishing boats and attacking oil tankers, and then bombing Iran.
It was estimated that in the first day alone the US burned through half its stock of some precision munitions.
The supply chain for those is years long.
If you were China, what would you be thinking right about now? Say, a vacation in Taiwan?
There's jack shit the US could do about it.
