Repelling Invaders

One of the most important functions of government, perhaps the most important of all, is to protect the country from attack, and that function is usually performed by the armed services, yet there has been no military action to prevent unruly crowds of youths from forcing entry into Britain through the Channel Tunnel.

My guess is that it would suffice for troops to open fire once. If they killed a few dozen; the survivors would then think of somewhere else to go.

Should ministers be unwilling to do that, an alternative deterrent would be an electrified fence maintained at a thousand volts or so, and sited inside the present fence so no one would come upon it unawares. Anyone electrocuted would clearly be the architect of his own doom, so there would be no risk of anyone feeling guilty, as some sensitive souls might after a shooting.
