according to my view PRC will never use the military option to re-occupy the Formosa island, Taiwanese is their own blood brother. She don't need 600's of warhead to strike that small island, even the leaders noted it's one of the option.

Other points:

The PRC is not an aggressor like the west done along of the history. Chinese people is a friendly people until they got attacked. So the military war between PRC and USA only be happened if the USA president doing a panic decision and secretly order the army to start to fire the missile as preemptive strike toward China.

And what will be happened? Maybe before the missiles come to China, USA had been devastated.

May be it's the real situation has been settled in the PRC's policy in her relation with USA and other countries. If we carefully observed some military incident from Beograd, Hainan, and the recent pacific sea, we can catch what I said here.

I do hope PRC will be save by the gospel as American. Chinese descendant was came from Abraham's wife whom separated from his descendant from Sarai. According to the book of Genesis Chapter 25 we'll find they were moved to the east land.

And if we think about the promise of God "YHWH" to Abraham, that his descendant will be as the sea sand, then we will find the Chinese represent the prophecy number. And if we brightly take the string we will accept that America and Chinese people was came from Abraham.

So there is no reason for the American and Chinese people to be enemy.

China can not yet be considered a superpower because its GDP per capita is not that large. In spite of the Communist label, wealth is polarised. Perhaps if the Chinese elite stopped buying US bonds and spent more on their own people, America would be forced to deal with its thoroughly unhealthy deficit.

As for Taiwan, has everybody forgotton that its population does not consist only of people who regard themselves as Chinese? Taiwan was populated long before Chang-kai-Sheck's exile.

Trying to force nations together usually ends in tears, ask the Scots, the Irish and the Welsh (and even the Cornish), and that's just the UK, the are plenty more examples internationally like Yugoslavia the USSR and the coming soon the E.U.

Remember the old saying, "Good fences make good neighbours".

You said: "It is important that Mr Obama is very clear about his intentions, as indecisiveness or hints of a change of position could be dangerous in such a situaiton."

I think you're indulging in a lot of wishful thinking here. He's not exactly demonstrated decisiveness over Afghanistan. Taking weeks to decide about troop levels and then coming out with a fudge that didnt please his supporters or his military commanders doesn't send the right signals overseas.

China's attitude on this has been very unimpressive for a long time. She would do well to learn from how Britain responded to calls from her colonies for independence, and note the friendly Commonwealth that resulted.

If push comes to shove the rest of the world should ask themselves who would they rather have as the World's only (or top) super power. For my money the USA is the best on offer, and likely to remain so for the foreseeable future.
