“The US had over 86,000 casualties in Vietnam in 1967.”
That was over a year, at the height of the war, not the first six months.
By that point in the Vietnam War, Russia and China were sending 300 tons of weapons and supplies per day down the Ho Chi Mihn Trail. Over 15,000 Soviet and 300,000 Chinese communists were serving in North Vietnam, including piloting combat aircraft against American forces. Thousands of howitzers had been provided, and millions of Artillery rounds.
Thank you. Everybody, in the flush of Russia’s own propaganda, seems to have forgotten that the predecessor state of today’s Russia supplied the weapons and the training to kill thousands of Americans in Korea and Vietnam. And we didn’t threaten to unleash Armageddon on them.
