Total gibberish. You can do better. The US did not lose these wars, the population was not behind the governments they backed because of corruption among other things. From a purely military standpoint, the US dominated in both the instances you described. There is a difference between winning the fighting and winning the hearts and minds of the people. And how well do you think a 100 year old cannon would do against a modern 155 mm howitzer? There is probably a point hiding in here somewhere, but for the life of me I don’t know what it is.
