On August 2-3, the US speaker of the House of Representatives, Nancy Pelosi, visited Taiwan for 16 hours. It was a visit of seismic proportions along the Pacific Ring of Fire. Speaker Pelosi became the highest-ranking US official to visit Taiwan since the unannounced stopover by then-speaker Newt Gingrich in 1997. China has reacted to speaker Pelosi’s visit by vehemently condemning the visit, noting that it will undertake “resolute, forceful, and effective” responses. Should we be concerned? The answer is yes.
