Could US hold out long aganst Russia and china?

That depends on how alert the USA is. She has had decades to plan her plans for an attack; and fortify against just about every conceivable scenario that Russia and China might engage against her including a combined Russian/Chinese frontal attack. Americas great weakness is that she is gullible and mostly asleep and open to surprise. Today, 2008, America is blinded by her great power and shiny military systems thinking that she is the best and that no one would ever attack her. The Chinese will know this and might perhaps seek to one day use it. America doesnt think like China does, so she is open to a sneak attack through complex deception scenariOS. China might invade Taiwan, then America gets sucked into the war, then China decides to seek peace agreements and the USA agrees, then without warning China might do a sudden attack upon the USA. Bingo...its over very quickly if America is so deceived. A combined attack by Russia and China would be over fast and the USA mostly broken. We need to pray for the USA. Without her... the forces of darkness would swamp the rest of the world mostly so. Pray for America. She needs our prayers. She needs someone in power, e.g. the President would be a great start, to encourage Christian revival to get God back on her side. *you might note: regarding the Chinese. Whereas the Americans are generally open and honest and straight shooting mostly so...the Chinese are different. Deception with them is a mind game so often. It is known in Australian banking circles that Chinese will keep agreements with each other (they will honour agreements between themselves) yet they will default (wont payback money etc) on agreements with westerners as it suits them. In truth there are no binding agreements with the Chinese that westerners can trust them to keep. Gibo.
