Not through legislation, or in today's world, executive order. The first amendment or what's left of it anyway, is too important. But you could still impose social sanctions. Ironically education might be the best solution, but the system we now have is what produced this sort of slogan in the first place!
As far as the videos being a stretch -- yeah, in a sense. But without the mindset implicit in the slogan, it might be harder to get people to sign up to kill other people. But as U.S. Marine Corp Major General Butler, the only Marine ever to win two Congressional Medals of Honor and a Brevet Medal, wrote in 1935 (!):
"I spent 33 years and four months in active military service and during that period I spent most of my time as a high class muscle man for Big Business, for Wall Street and the bankers. In short, I was a racketeer, a gangster for capitalism. I helped make Mexico and especially Tampico safe for American oil interests in 1914. I helped make Haiti and Cuba a decent place for the National City Bank boys to collect revenues in. I helped in the raping of half a dozen Central American republics for the benefit of Wall Street. I helped purify Nicaragua for the International Banking House of Brown Brothers in 1902-1912. I brought light to the Dominican Republic for the American sugar interests in 1916. I helped make Honduras right for the American fruit companies in 1903. In China in 1927 I helped see to it that Standard Oil went on its way unmolested. Looking back on it, I might have given Al Capone a few hints. The best he could do was to operate his racket in three districts. I operated on three continents."
Pretty much the same points made in the second video three and a half decades later. Interesting that our govt. still uses the military for the same purposes, they've just gotten better at selling it. Now we are exporting "freedom and democracy" at the same time that those concepts are disappearing rapidly in our "homeland."
