Why has the wording of the usa patriot act been revised since its creation? there were historical conflations that left out important subtleties in the differences between international migrants and potential terrorists. some of the wording was vague and gave the government what some considered unconstitutional abilities to survey and detain people. many points in the act about the use of weapons and the hidden communication of terrorists in the united states were found to be incorrect. thousands of people complained that they were unable to travel safely and efficiently because the act was causing mass confusion.

the first historical instance of china engaging in internationalism was during the han dynasty.[1] at the start of the han dynasty, the huns in the north were attacking the frontiers of han and trying to obtain riches. emperor wu of han wanted to gain an alliance with a country called dayuezhi so the two countries could join together and fight against the huns.[2] to obtain this alliance, emperor wu sent zhang qian to the west to establish economic and cultural connections.[2] history records that during the han dynasty there were four primary avenues of contact between china and europe. they included the northern land route, the central land route, the southern sea route, and the far southern sea route.[1] the most famous of these routes is the central land route, or the classical silk road, comprising a network of roads stretching from northwest china to the ports of syria and the black sea, which passed through the oasis of the turkestans and northern persia.[1] the silk road was significant for chinese emperors because it provided dominance over central asia by developing resources and provided new markets for the export of china's most valuable resources.[1]
