1. Consider the current composition of the US economy. Gross Manufacturing is being treated as a commodity, with foreign (namely Asian) labor being the definitive cost factor in choosing where to have such work performed. Manufacturing is being abandoned and "offshored" at a brisk pace, for lack of competitive domestic offsets. In summary, the US economy is removing manufacturing as the underlying source of wealth-building feedstock and relying upon service-sector jobs to form the backbone of the economy.

2. Consider the USA's "Arsenal of Democracy" effort during WWII. The Lend-Lease agreements and outright raw ability to place more "beans, boots, and bullets" in the hands of our soldiers were often the contributing factors in Allied victories during countless battles. (Perhaps too simplistic an analysis?)
The fact remains that the US manufacturing effort to supply the conflict was a huge undertaking, a represents something of a "golden age" in US factory output.

3. Considering both items 1 and 2, is your opinion that the US is rendering itself strategically vulnerable and perhaps endangering its sovereignty by placing faith in continued warm Sino-US relationships?

The relationship may be even considered adversarial at times in light of issues such as Taiwanese Independence, Petroleum entitlements, and Chinese wargaming.

The root of my question is this:
Is the US capable of supplying itself in a war on the scale of a World War through domestic manufacturing, or must we now consider the political motivations of China in order to meet the scale-up in obtaining the proper material to outfit our fighting forces?

Again, I appreciate your insight in this question and I apologize for my lack of nomenclature and form in posing it…
