It is the change of technology and not the mere change in times that requies a changed approach. The Brits and other eighteenth century powers, if tempted to tangle with the US in the 1770s, 1780s, 1790s or even in the War of 1812, did not have intercontinental ballistic missiles, intercontinental bombers, nuclear weapons, fleets of nuclear missile and nuclear attack submarines in every ocean and able to closely approach our coasts and our population centers, suitcase nukes, and a wide variety of other innovations. Also, few Brits had the fanatacism of the Jihadists who blow themselves up to take other people’s children with them. You are so overcome by nostalgia for the late eighteenth century that the mist in your eyes has bli=nded you. Of course, you are a paleo and so that goes without saying. Reality is not your strong suit.
LOL...well did you know Hitler couldn’t even take out the Brits in WW2?
There is nothing in the change in technology that justifies us changing our policy of leaving other nations alone to handle their own internal issues.
Principles remain the same no matter what era we are in, that is what the Declaration and Bill of Rights are about.
