Well, the thing is that what they US has done has not been very effective at driving Taiwan towards a higher level of conflict with the Mainland. They (the US) probably wanted to, but they are not succeeding.
Besides, the more I am beginning to see the connection between the "national character" (民族性) reflected by the average everyday Ukrainians (and Russian) I encounter in my life to their countries/regime's behavior, as comparing to that of Taiwanese/Mainlander to their respective government/regime's behavior. I see less and less possibility that Taiwan will be blunt enough to actually push for a real war/conflict with the Mainland, nor is the Mainland right now bothered to go for Wutong unprovoked at the moment.
Peace still have way too much of a dividend for both side that the US has nothing even closely equivalent to offer for either side to abandon peace. Remember, it is the DPP in power right now. They could even just taunt a referendum, and that will be enough to escalate the confrontation.
But NO, the Taiwan leadership simply wave off any real provocation towards the Mainland, as a matter of principle, leaving only the small meaningless gestures for domestic consumption. The very fact that DPP leadership seemingly abandoned their pursuit of a "properly name Taiwan" (台湾正名) campaign, and instead taking very cautious and conservative approach, should be clear evidence of my point.
Taiwan's society is essentially very Southern Chinese, in which they have a rather low sense of a "holy war" zealotry as evident in many culture with strong messianic religious traditions.
