That extended a campaign that had crimped a vital sea lane for two years and drew the U.S. into pitched naval battles.

It’s not a crazy idea; the island, which lies along Arctic sea lanes and holds vast reserves of oil and rare earth minerals, would be a major strategic asset.

An area of long-simmering disputes, the South China Sea serves a key sea lane for global trade.

That's not far from Yemen, where the pro-Iranian Houthis now control much of the nation and have recently interrupted international sea lanes, resulting in air strikes by U.S. and British planes.

The strikes were intended to degrade the Iran-backed militants’ ability to attack ships in sea lanes that are critical for global trade, a campaign they have carried out for almost four months.
