This is a good observation. The same situation already exists in the USA, and there are many foreign troops here as many citizens have testified. Do a google search on UN troops or vehicles and you can pull up photos, or search for the unidentified bases newly constructed here on our soil. They are not trying too hard to remain hidden. I have friends who spoken to several of these foreign soldiers who are here, and they do not hide the fact. Why would there be foreign soldiers here? Same reason there are "foreign" soldiers in Israel. It will be difficult for the military to fire upon their own people, but we have seen many times that "peace-keeping" troops from many countries that make up the UN forces have no such qualms. Does Kosovo, Bosnia, Afghanistan, or Iraq ring a bell? A conspiracy theory is no longer a theory when it is a proven fact. The psalmist foretold this worldwide conspiracy against the Lord:
 
  "Why do the heathen rage, and the people imagine a vain thing? The kings of the earth set themselves, and the rulers take counsel together, against the Lord, and against his anointed, saying: Let us break their bands asunder; and cast away their cords from us.He that sitteth in the heavens shall laugh: the Lord shall have them in derision.Then shall he speak unto them in hsi wrath, and vex them in his sore displeasure.Yet have I set my king upon my holy hill of Zion.I will declare the decree; the Lord hath said unto me, "Thou are my Son; this day I have begotten thee.Ask of me, and I shall give thee the heathen for thine inheritance, and the uttermost parts of the earth for thy possession.Thou shalt break them with a rod of iron: thou shalt dash them in pieces like a potters vessel. Be wise now therefore, O ye kings, be instructed, ye judges of the earth. Serve the Lord with fear, and rejoice with trembling. Kiss the Son, lest he be angry, and ye perish from the way, when his wrath is kindled but a little. Blessed are all they that put their trust in him."  Ps. 2:1-12
