XBob, this is exactly what I told you. The single plant that makes 5.56mm that is owned by the military is insufficient for wartime (not the only 5.56mm manufacturer, in the U.S. or otherwise). They are currently contracting with private sources, and I provided you two, one in the U.S., one that is not. This is a cost issue. If they wanted to have all the bullets from U.S. suppliers they could. This has nothing to do with trade to China. Trade with China isn't why the Army owned only one factory making 5.56mm ammunition. That was the case because we hadn't been in any conflict over a month long for three decades. There are plenty of ammunition manufacturers in the U.S., and if the Army wants to build more facilities (of it's own), or buy from those U.S. (or even allied, such as Israel) producers, they can. This is like earlier when you through up a series of unrelated statistics. You're obfuscating.
You are making two implicit assumptions. Those are:
1) That we will have time to build such facilities
2) That the supply lines will remain secure if we must import the material from elsewhere.
What if the next conflict is a come as you are party? What if we don't have the luxury of a year or more to build these factories?
We are cutting our own throat, all to keep the free traitors happy. Those free traitors may cause the fall of this great nation, as the term for them implies.
