It looks like Ukraine will be given permission to produce Patriot missiles, but likely not the best kind which they most need to protect their cities from Russian ballistic missiles.
It could take a long time to actually start producing missiles.
Trump is cool with Iran having ballistic missiles because other countries in the region have them. He’s acting like Iran is just another country and not a unique threat.
Limited patriot missiles may not hurt the US too much in a war with China because China will likely overwhelm patriot batteries, and destroy those batteries in one day. Without batteries to fire the missiles, the missiles are useless.
One reason the US does not build that many missiles in a year is because the fuel in missiles degrades and makes the missiles too dangerous to fire, meaning, if we build a whole lot during peacetime, most of the missiles will go in the trash along with the piles of money it cost to purchase them.
Trump has left Europe looking for alternatives to US weapons, even if they are worse, weakening the alliance and losing US sales. If the world does take big strides away from US weapons, the US will have lost a lot of leverage.
