They already had "trainers" on Taiwan for that. There is no additional value to tripwire forces in Kinmen since there is no circumstance where Kinmen would be liberated but Taiwan would not be liberated.I was thinking it more like in case of conflict where US wants to get involved against China, it would be an easier sell to the American public that 'US troops have been attacked in Taiwan' versus 'Taiwan has been attacked'.
However there is immense value in barrier troops in Kinmen, since historically, it has been where the most ROC troops have defected to mainland China.
Kinmen is also the most resistant to Taiwan's independence regime, as they have called for expelling Taiwanese troops from Kinmen.
That lingering potential for invasion might make it seem like an unlikely place to construct a bridge to mainland China. Except, that’s exactly what many residents are calling for.
The idea of a bridge to mainland China is part of a wider proposal, unveiled in full earlier this year by a cross-party alliance of eight local councilors, to turn Kinmen into a demilitarized zone (DMZ) – or so-called “peace island.”
The proposal envisages removing all of Taiwan’s troops and military installations from the islands and turning Kinmen into a setting for Beijing-Taipei talks aimed at “de-escalating tensions.” It sees the bridge, which would stretch between Kinmen and Xiamen, as a way of boosting economic ties.
