We do not need a trade war with China. Not now, not really ever, but especially not in the middle of a recession. Looks like one might be starting. They waited a whopping 48 hours after Prez O set trade barriers (tariffs) on tires. This is all right before the G-20 meetings (which China will atend) start in Pittsburgh on the 20th of September.
There is an old phrase that goes "when goods stop crossing borders, bombs cross borders".
