Was it all a bluff?

Balance of Power From FOLLOW US SUBSCRIBE   Was it all a bluff? After news leaked that President Donald Trump approved and then called off U.S. airstrikes on Iran last night, it emerged he'd warned Tehran about an imminent attack while insisting he was against a war. Today, as airlines began re-routing flights away from the Strait of Hormuz, Iran's Foreign Ministry called in the Swiss ambassador, who also represents U.S. interests, for talks. Was the outreach why Trump abandoned the strikes? Or was this the latest example of the whipsaw approach from a president who's twice attacked Syria but also backed away from using force after lashing out at Iran and North Korea? The leak of Trump's about-face also speaks volumes about the battle for influence in the White House. Hardliners clearly thought they'd convinced him to back a tough response to Iran's downing of a U.S. Navy drone. Yet Trump was elected on a pledge to pull out of Middle East wars. The president, who governs with the cliffhanger style of his Apprentice TV show, thrives on keeping supporters hooked on dramatic twists. But as his 2020 re-election campaign gains steam, the stakes now include the prospect of armed conflict and instability in a region that supplies a third of the world's oil. - Anthony Halpin  The US FAA has issued a notice prohibiting US carriers from operating in areas above the Persian Gulf and Gulf of Oman.

The former Delaware senator's struggles to defend his remarks this week about finding common ground with two segregationists is an early sign of the trouble he could have explaining a complicated voting record and his nostalgia for a Washington collegiality that has steadily diminished since he was first elected in 1972. Border control | Trump praised Mexico's efforts to crack down on migrants crossing the border into the U.S. after the two countries entered an agreement aimed at stemming the flow of people entering Mexico from Central America. Mexico will take greater control of its southern border and ask foreigners to register their arrival. Osaka drama | Before Trump, Group of 20 summits were dull if worthy affairs. This year's gathering in Osaka, Japan next week promises to be anything but, as the U.S. president holds talks with China's Xi Jinping after threatening to escalate their trade conflict. The best-case scenario would be a pause in new U.S. tariffs and a resumption of negotiations that broke down in May. The worst-case would be a new Cold War between the two largest economies. Favorites flushed | European Union leaders cast aside the candidates who've dominated the race to head the next EU Commission and will start from scratch less than two weeks before a self-imposed deadline. The decision at a summit in Brussels extends gridlock that has left investors in the dark over a series of critical posts including the next president of the European Central Bank. Bad air | As climate change tops political agendas from Washington to New Delhi, there's no solution in sight for the bad air choking Europe's poorest countries. While the EU has focused mostly on stability in the volatile Balkans, health problems and lost productivity from air pollution cost the continent more than 10 billion euros a year. Obsolete coal plants and cars spew smog and hundreds of thousands of people burn tires, wood and trash to stay warm. What to watch Boris Johnson and Jeremy Hunt will go head-to-head in the contest to become the U.K.'s next prime minister as they seek votes from the Conservative Party's 160,000 grassroots members over the next month. Ukraine's Constitutional Court threw out a challenge to a decree by President Volodymyr Zelenskiy ordering early parliamentary elections. The ruling confirmed a vote will take place next month and a new government should be in place by the fall. Turkey reruns the election for mayor of Istanbul on Sunday, pitting former prime minister and ruling AK Party candidate Binali Yildirim against opposition challenger Ekrem Imamoglu, who was stripped of his narrow victory in the March 31 ballot. And finally...The U.K. is poised to generate more energy from low-carbon sources than from fossil fuels for the first time since the Industrial Revolution. Wind, solar, hydro and nuclear plants provided 48% of the nation's power in the first five months of this year. The U.K. has gone without burning coal, the dirtiest fossil fuel, for the equivalent of 80 days so far in 2019, including one stretch of 18 days in a row.
