Cross-strait tie: Is Lai losing support in Taiwan?

Beijing has strongly rejected Taiwan leader Lai Ching-te's latest remarks on cross-Strait relations, accusing him of repackaging "Taiwan independence" in the language of peace and democracy. The comments come as Lai faces mounting political pressure on the island, after Taiwan's legislature voted on an impeachment motion against him. Meanwhile, US President Donald Trump has warned against Taiwan independence and calls Taiwan a "problem." Where does the Taiwan question stand amid these developments? Why is Washington's opposition to Taiwan independence a positive step toward peace and stability in the region? And what's the message sent by Washington if arms sales continue?
