For the first time in American history, the US government allowed Chinese soldiers to land on American soil. The Chinese soldiers were present in Hawaii as part of a military exercise. The first two links [1, 2] describe this event in more detail while the third link, from the establishment Washington Post, has a minimalist mention of it.
Ostensibly, the joint maneuvers were to allow the two militaries to practice together for such things as disaster relief and joint humanitarian missions. However, there is one major reality which “screams” that this objective was not a real goal for the Chinese government or for its military participants. The Philippines, a nation practically on China’s doorstep, has been devastated by a massive typhoon and humanitarian relief efforts are desperately needed. The US Navy redirected warships to send relief to wrecked Philipino communities. If China had a real interest in working together with the USA on joint humanitarian missions, here was China’s “real world” test to do such a thing. What happened? The last link shows that China’s donations to the Philipino relief efforts was almost nothing. Given that China has immense financial resources and is very near to the Philippines, it could have taken a lead role if it actually cared about humanitarian missions. The link notes that the Scandinavian furniture company, IKEA, donated more than the entire nation of China to the Philipino relief effort.
This tells me that China’s real interest in sending a military unit to be present on American soil was not to train for joint humanitarian missions. They were, in my opinion, eager to send their military observers to the USA to “spy out the land” for a future Chinese war against the USA. The links also note that Russian soldiers were allowed by the Obama administration to be present in Colorado as well. Colorado is where the NORAD headquarters have been for decades at Cheyenne Mountain in Colorado Springs and Hawaii is very militarily important due to its Pearl Harbor naval base and military airbases. I’d bet that all such Russians sent to Colorado were experienced and/or trained Spetsnaz troops who were all “eyes and ears” for militarily significant targets, weak infrastructure locations, flat zones where improvised air strips could be quickly located, etc. I’ll bet the Chinese troops visiting Hawaii had the same purpose.
I wonder if there are any reciprocal plans from Russia or China for US military troops and observers to be invited to tour militarily-sensitive areas of Russia and China? If not, then this is a foolish one-way sign of weakness on the part of Obama and the USA.  
Ezekiel 38-39 foretell that Russia and China will spearhead an attack at the very end of our age against the latter-day nations of the house of Israel (the ten tribes of Israel, not the Jews–who are the house of Judah in biblical terminology). The modern nations of the ten tribes of Israel, as my books, articles, and audio messages make clear, are the USA, the UK, Canada, Australia, New Zealand, the Scandinavian nations and many mainland European nations. These nations will be the targets of the Gog-Magog attack described in considerable detail in Ezekiel 38-39. See my articles, The USA in Biblical Prophecy and What Ezekiel 38-39 Reveal about a Future World War III, for more information. Much more information documenting the locations of the modern nations of the “house of Israel” can be read in my books. Many of the major points of those books can be heard by listening to my audio messages on this subject. The truth on this topic is so easily-seen that you need not have any “faith” to see the persuasive, but long-hidden, historical evidence on this subject.
The invitation by the US government to bring soldiers of rival nations to American soil and see our land and its bounty reminds me of a biblical account. A king of Judah name Hezekiah invited a Babylonian delegation to tour all the best that was to be seen in the kingdom of Judah (II Kings 20:12-18). The prophet Isaiah told the king that he had been a fool as all he had accomplished was to instill a desire in the Babylonians to invade Judah and carry away all its wealth. I wonder if President Obama is now playing the modern role of Hezekiah in inviting Russian and Chinese military contingents to the USA to see America and all its wealth. Ezekiel 38-39 prophesy that Russia, China and their allies will, like the Babylonians of old, eventually invade to seize all of America’ wealth. Ezekiel 38:11-13 reveal that seizing our wealth is exactly the motive of the invading Russians, Chinese and their allies when their future “Red Dawn” movie attack scenario becomes a reality.
