The two sources, written by Peter Navarro and Kent Lassman, discuss trade policy. Navarro, a trade protectionist, argues that America's trade deficit is detrimental to the country's economic and national security, citing China's economic aggression and the unfair trade practices of other countries. He proposes a series of measures to reduce the trade deficit, including tariffs, restrictions on Chinese investment, and visa limitations for Chinese students. Lassman, a free trader, asserts that trade benefits America's economy, promotes international cooperation, and bolsters national security. He argues that the Trump administration's tariffs have been detrimental, and he recommends a strategy of openness and liberalization to increase American prosperity.
