Now, our Second Amendment was set up to prevent the possible future rise of a tyrannical government. Yeah, times have changed and the puny .223 platform isn't much against drones, tanks, aircraft, etc. Still yet, look around the world at places where people are throwing rocks and molotov cocktails in protest against same tyrannical governments.
The U.S. Government responded to Britain's peril as well with passage of the Lend-Lease Act in March 1941. Almost immediately, quantities of "U.S. Rifle, Cal. .30, M1" were on their way across the Atlantic, and those guns are the subject of an article by noted M1 Garand historian Scott Duff starting on p. 42. The "British Garands" have an interesting history but the importance of arming the British at that time is made clear by the fact that the rapidly growing U.S. Army itself did not have sufficient numbers of the then-new M1 Garands. Winston Churchill wrote in Their Finest Hour: "When the ships from America approached our shores with their priceless arms, special trains were waiting in all ports to receive their cargoes. The Home Guard in every county, in every village, sat up through the night to receive them. ... By the end of July we were an armed nation ... ."
Now, sadly, Britain is again a disarmed nation, where even Olympic athletes wanting to represent their country cannot own a handgun and where an act of self-defense can land a subject in jail. As with virtually all rifles and handguns, those likely few remaining guns sent to England in its time of desperate need have been confiscated and destroyed. Despite the very near enslavement of England being so close a mere six decades ago, the lesson of the false promises of gun control and personal disarmament were not learned.
