Yet, so many US consumers take a knee to Chinese imports.
Format: Kindle
My first response to Lee Smith's "The Chinese Matrix" is anger with the CCP. But, they did what treasonous US politicians and investors permitted in exchange for wealth and power. The current situation reminds me of the Chinese finger trap - a small tube of woven reeds just large enough to insert a finger into each end. When naturally trying to withdraw the fingers from opposite ends, the woven reeds constricted. Escape was contrary to natural instinct. Likewise, to extract our country from the Chinese Matrix will require unnatural sacrifice.

Comprehensive and bold analysis of US foreign policy with China.
Format: Kindle
Lee Smith takes the reader through the many years of China appeasement from Kissenger and Nixon to the present where China continues to suck the power of the US toward its goal of global domination.

A must read for Greek history!
Format: Hardcover
A lot details about Thucydides himself and the history around himself with great insight into all the wars including the long Pelopnnesian war. A must read for history lovers. R.W. writes so that a "lay person" can understand all the intricate details of the greater Greek conflicts, and politics during this time in history.
