WASHINGTON: Will London's new Muslim mayor Sadiq Khan be allowed to travel to the United States? Perhaps not, if Donald Trump is elected President.The presumptive Republican candidate has reiterated his pledge to ban Muslims from entering the US, saying he doesn't care if it hurts him in the general election."I don't care if it hurts me," Trump said on MSNBC's "Morning Joe" this week, some 48 hours before Khan's election. "I'm doing the right thing when I do this. And whether it's Muslim or whether it's something else, I have to do the right thing, and that's the way I've been guided."Although he was not specifically asked about Khan's election, Trump called his Muslim ban proposal "common sense", rambling, "We have to be careful. I mean, we're allowing thousands of people to come into our country, thousands and thousands of people being placed all over the country that frankly nobody knows who they are. They don't have documentation in many cases — in most cases. And we don't know what we're doing."But he has never really qualified that the ban proposal is only for undocumented Muslims, although he softened his initial call for a blanket ban by saying US citizens who are Muslims and leaders of Muslim nations may be excepted. By that token, Sadiq Khan may or may not make the cut.It's just one of the several bizarre and seemingly off-the-cuff policy prescriptions Trump has thrown out, improvising as he gallops along his slash-and-burn presidential campaign.On Friday, he alarmed the financial world by suggesting that the United States could renege its debt obligations simply because of its economic heft and promise — he would simply ask creditors to take less!"I would borrow, knowing that if the economy crashed, you could make a deal," he said on CNBC, adding that it had worked for him in his career as a "swashbuckling" businessman. "And if the economy was good, it was good. So, therefore, you can't lose." The idea left economists gobsmacked. The United States is able to borrow money at very low interest rates because its Treasury securities are regarded as the world's safest investment and foreign governments buy billions of dollars of it. Renegotiating one of the safest financial securities after crashing the economy could undermine the global financial system, one economist said, adding, "this is not a hotel or a casino." President Obama himself pitched in , warning that the presidential campaign and the White House occupancy was not a reality show or entertainment, but a "serious job … in serious times.""You know, if they (candidates) take a position on international issues that could threaten war or has the potential of upending our critical relationships with other countries or would potentially break the financial system, that needs to be reported on," Obama said, implicitly criticizing the media for not calling out Trump."What I'm concerned about is the degree to which reporting and information starts emphasizing the spectacle and the circus, because that's not something we can afford."
