In May of 1940, with tensions increasing in Europe and the German invasion of Poland, France and Germany prepared themselves for another Great War. The French had built the Maginot Line, a massive fortification of bunkers and artillery emplacements along the French German border and anticipated a long and bloody conflict, much like they fought in WWI.

It never came.

Instead, the Germans had developed what they called the “Blitzkrieg” and what we now know to be modern mechanized warfare. They had mobilized their infantry, bypassing the Maginot line and quickly caught the French flatfooted with an end-around through Belgium. The British Expeditionary Force was forced to retreat home with their tail between their legs, and the German won a stunning military victory.

The French lost their country, not necessarily due to poor planning or a lack of military reserves; they simply were not prepared to fight “tomorrow’s” war, because they were still fighting “yesterday’s war,” planning for a repeat of WWI. In fact, most huge military losses throughout the course of history, were due to the loser fighting a war that didn’t exist anymore; from Wallace’s loss at Falkirk to Russia’s loss in Afghanistan.

And now, ‘tomorrow’s war’ is upon us again.

This time it’s not being fought with guns or knives or even armed troops. The powers that be in this world are now raging a war in the financial markets and court systems in our nation’s backyards. It’s being fought for the same reasons most wars are fought — money and power — but it is foolish not to recognize it for what it is, a war.

There are very powerful people in this world, and they are much like the monarchs of old. They seek to expand their power, domain and influence. They are fighting the war with the pen and using the legal system and financial elements to establish dictatorial like powers over the masses, instead of using troops.

They are the George Soros’ of the world, and other people who we have not seen yet that are influencing the systems of the world to increase their stature. Like King Edward at Falkirk, they are using technology and fighting “tomorrow’s war” while we are left standing flat-footed expecting our carriers and tanks to protect us.

They can’t.

The power of an idea is one of the most deadly weapons you can use in a free society. They are using their money and influence to buy ideas in the marketplace, and then use them as weapons against what is standing in their way of them and their grab for power.

American freedom. Capitalism. Our Constitution.

All of them are under attack daily from these nefarious elements, in a war we had better get started fighting. They know that as long as people can do what they want, and when they want, they will never have full control of governments. They seek to destroy the will of the American people and their laws. They turn things upside down in an effort to tear down the idea that each of us is free to live a self-determined life, that all men are equal under the eyes of the law, and that we are all free to decide our own destinies.

Up is down. Black is white.

Every idea that could pose a threat to them is being systematically attacked and destroyed. They use the power of regulation to determine how and where our financial markets operate. They pack our court system with left leaning judges to circumvent the rule of law and the Constitution. They convince us that the world is doomed by the very act of acting freely — the green movement. By doing so, they increase their sway over our lives.

It’s time to fight back. Each individual must understand that this fight is not fought with guns, but with ideas. We need to start at the community level, in the same way our enemies did. Talk to our neighbors; make them understand the dangers of a government that would tell us how to live our lives. Write to our Congressmen and vote them out if they don’t start working to dismantle the machines of our enemies — the machine of big government.

Defending our Constitution has never become so important.

In November, America is probably facing the most important election since our Civil War. It will define us as a nation — do we stand for freedom of will and the Constitution, or do we surrender ourselves to the Philistines and allow them to direct our lives under the false idol of safety, security and protection? It’s not too late, just as it wasn’t too late when the British left at Dunkirk. Battles have been lost, but not the war, not yet.

Do we let the King come back to power to defend us, or do we pick up the pitchforks and defend ourselves, and — in turn, live our lives free from feudal rule?

It’s your decision.

Fight ‘tomorrow’s war’ in your neighborhood today, or we will end up tucking tail and running across the English channel and losing because we are still fighting “yesterday’s war.”
