The Depression had already hit after a stock market crash that led to hyperinflation. International investors, arms dealers and false prophets" of propaganda also had to be manufactured be they real or not. But, that wasn't all that had to happen. Proxy wars had to be fought to test new re-armament weapons of mass destruction on civilian populations as in Spain, Ethiopia ,Libya, "Free" China and Southeast Asia. For those who were looking to pull themselves out of the shock of the Great Depression, annexing and re-annexing former lands or new lands for resources had to be found. Germany formed it's Anchluss and Lebensraum programs while Japan sought rich minerals and petroleum resources in Southeast Asia. Thus the world had laid the pretext for all out aggression. The only thing needed were choosing up sides. Thus, the Axis and Allies powers squared off.
This picture is not too different than that of today's scenario occurring around the globe. China for it's own nationalistic interests has sought to annex(or re-annex) the Spratly Islands of the Phillipines which along with Vietnam, Malaysia, Brunei and Taiwan are all making a bid for the mineral rich island/rocks. China is determined to undermine Japan's sovereignty to the Senkaku and Diaoyu Islands for similar purposes of rich mineral resources there. However, China, Russia and South Korea are perplexed by the U.S. presence in the South Pacific pressuring the nation to "blink" in the wake of the Spartly Islands stand off and also recently from the placement of U.S. THAAD missiles on South Korean soil. North Korea has responded with the firing of more "warning" missiles. examples With these a new "Triangle of Death" has potentially opened up.
Other opening theaters of potential war are on the Indian Subcontinent and Southeast Asia where pro-Democratic forces of Myanmar is displacing it's Islamic inhabitants as China's Uighur(pronounced wiggers) are being displaced. India and Pakistan are at odds continuously between the Punjab and Kashmir. India is at odds at the border with China.
the Middle East and North Africa are all ablaze, enough said.
The Baltic regions are inviting aggression as pro-Western forces with NATO feel obliged to demonstrate it's resolve by supporting the stance with the Ukraine while arming Poland, Estonia, Latvia and Lithuania. A prescription for potential disaster as Russia feels threatened by military maneuvers there.
So, far the America's have seemed unreachable until the sudden presence of terrorist attacks at the beginning of the 21st century. The "open" borders may not only prove a political issue for the U.S. Presidential election , but also one for military exercises as the southern borders appear porous enough to invite a threats of some form of attack.
Last, but not least is the areas designated by both Zibegniew Brezinski and Collin Powell as the "Great Game" or what we call Central Asia and Eurasia. It's wealth of minerals, oil and strategic locations along with the religious tensions makes it a hotbed for several small fires coalescing into a grand conflagration.
The world's economic collapse in 2008, shifting tides of nations destabilized, their populations displaced or depopulated adds to the chaos of the world unable to handle the logistical errors of already a vulnerable world situation.
The crisis grows along with climate changes and extreme demographic shifts due to displaced populations do not house people as workers, farmers. Both bombed out lands and environmental disasters lay waste to lands that can not be used for practically anything for several years or decades.
It is time to tie in all of our problems as one effecting our one Earth and understand that what happens in one country effects those living in another thousands of miles away, although maybe not either initially or even simultaneously at first, but time is relative in a global world with a global economy. It is time to meet at the table of reason before we repeat the mistakes of our bloody past!
