Our borders are very porous Hannes and they leak like a sieve. Some minister, or department had a wire fence built that cost millions and the fence is scrap, as the intruders simply cut it open and enter the country. Now with the Covid, they have the army patrolling the closed borders, but how do you protect a border that is thousands of killometers long?
Either a wall like China that is going to cost astronomical ammounts if you include the corruption costs, or I think a better option would be drones (with night vision cameras) and a squadron of reaction helicopters.
By the time that the virus is over you will have your van with a bed in the back and you can take long trips anywhere methinks 😉
Cheers and thanks!
