The rising nation was full of self-confidence and determined to expand. Its neighbor refused to negotiate in a bitter territorial dispute, convinced there was no legitimate issue to discuss. The new entrant to the international order also challenged the world’s greatest global power, which was forced to decide whether war could be justified against a country thousands of miles from home. The upstart’s territorial claims were excessive, but no one desired a rerun of past conflicts.



The year was 1845. The United States had absorbed Texas after the latter’s violent secession from Mexico; Washington demanded its neighbor’s acquiescence not only to the errant territory’s annexation but also to a new national boundary set well beyond Anglo settlements. The United States backed its position with provocative military maneuvers, occupying disputed territory. War soon resulted.
Around the same time Washington took an equally truculent position in dealing with Great Britain over the far western boundary between America and Canada. Where prior agreements had left ambiguity, the United States saw certainty. Some Americans proclaimed “54-40 or fight,” wanting to push the Oregon border up to the Russian territory (Alaska) later sold to the United States. The Polk administration took a less extreme position and London accommodated the arrogant juvenile nation, a necessary step in ultimately developing the “special relationship” between onetime enemies.
Today Beijing’s actions in the East Asian waters have a similar feel. The international and regional order is under strain as the People’s Republic of China (PRC) has become an economic colossus with growing military might and diplomatic influence. Control of islands offer resource ownership and maritime primacy, encouraging the PRC to assert territorial claims once considered impractical or worthless.
