You must understand that in the grand scheme of things, small entities such as Taiwan do not really have that much to say about their own destiny. While Taiwan is touted as a Democracy, first and foremost, the results of the election must serve the U.S. interests. The interests of Taiwan is subservient to the U.S. interest. U. S. interests changes with time and different presidents. What was the correct stand for the interests of the U.S. once upon a time would run afoul of U.S. interests later. At that time, Taiwan government would have to change their stands.I always felt this schizophrenia was the most dangerous disease for Taiwan.
As you said, everyone wants independence, yet no one expects to fight for it.
CSB did try to push for independence behind the scenes, but was basically told to sit down by George W Bush administration. They were busy with their Middle East agenda.
The problem with Taiwan is that they are too scared to let go of "Daddy America's" hand. If a Taiwanese government was daring enough to guarantee "No Alliance with America" as a precondition to settling the cross-strait issue, what would PRC do? Maybe the US won't let them behind the scenes? I always thought Ma Ying Jeou had a very bold idea with his Free Trade plan. I do feel very strongly that the "Sunflower movement" that torpedoed it was unleashed by the US. Any formalization of a framework between 2 sides is one step closer to resolving differences.
The US greatest nightmare: If a consensus was reached where there would still be a ROC military, but a small PLA base would be stationed on the island (like Guantanamo), anda joint "United China" operations division staffed with personnel from both sides was established. Almost everything else remains the same politically (with the exception of a PRC veto over ROC foreign affairs), everyone pats themselves on the back and says good job and goes home. Lockheed Martin, Raytheon, and other US MIC companies are left trying to explain to their shareholders why revenues decreased by 2 billion YoY.
Notice what happened to CSB. He was convicted after he lost the election and put in jail. This involves the Swiss banks divulging his bank account to the Ma government. Do you think either the Ma government or the Swiss would do this without the U.S. blessing? He went against the U.S. interests at the time and paid a price for his actions.
So any illusion about Taiwan allowing PLA into Taiwan without the U.S. blessing is simply a dream. There may be a day when the U.S. allow this. That would be a day when the U.S. and China worked out some deal under the table. Taiwan is simply a pawn in this scheme. What Taiwan wants or what is in its own interests is irrelevant.
