And, in what countries do the majority of illegal aliens arrive via aircraft??

The United States.

Visa Overstays account for 44% by the most recent count, but that is only the number that can be confirmed, with many more unconfirmed, likely putting this number over 50%. Also understand also that large numbers of otherwise temporary illegal aliens get "trapped" with an increase in physical barriers, further inflating the number of illegals who would not otherwise be in the US. This has been widely studied and you can research yourself, since it is outside the scope of a firearms discussion.

It wasn't a 'new idea', it's been implemented for decades, as well as supported, reinforced, supplemented, etc.

Further, the 'wall' has simply been a broad brush term to cover a multitude of physical barriers as well as electronic surveillance.

I am specifically reffing to the "30' concrete wall" certain politicians have touted.

You just refuted your own argument and don't even know it
Further, if physical barriers are 'so easily defeated', why have they worked so well when/where erected? At no point, and at no time, has anyone suggested physical barriers cannot be defeated, people have escaped some of the most secure prisons ever built. But to keep repeating BS talking points says a lot about you and your capacity for critical thought.

Walls only work with constant surveillance. Without constant surveillance, a wall is next to useless. Critical thinking includes looking at history (even recent history). As soon as surveillance of the Berlin Wall ended, it was defeated within minutes.

You've clearly never heard the term 'force multiplier'
Physical barriers are huge force multipliers, especially when COMBINED with electronic walls
Which AGAIN, have always been part of the equation

I clearly understand the term, and have alluded to it multiple times above. There are other force multipliers outside of physical barriers (especially on the scale we are speaking of) as well, and ones that are potentially much more effective. Physical barriers are of course not wholly ineffective when paired with force multipliers like surveillance and human intelligence, they just have to be employed in an intelligent and measured manner.

Your tone, however, indicates a certain close-mindedness on this subject. So there is no point in further debate on this subject, and I will refrain from such.

This thread need to be swung back into the direction of military service weapon adoption and the economics/politics/priorities associated with it.
