...start with an uncomfortable and increasingly important truth: flying's pretty tough on the environment. Sure, today's aircraft are some 70% more fuel efficient than planes operating in 1970. But passenger numbers are soaring: the industry[an error occurred while processing this directive] expects to fly 2.2 billion this year, 10% more than in 2005. The result? Aviation's share of global CO2 emissions, now around 2%, is expected to hit 3% by 2050. Problem is, flying is often the only way to go. Four-fifths of airline-related emissions come from journeys over 1,500 km, for which...
...world? The United States? The U.S. Administration is not the entire world. Europe does not account for one-twentieth of the entire world. When I studied the provisions of the NPT [Nuclear Nonproliferation Treaty], nowhere did I see it written that in order to produce nuclear fuel, we need to win the support or the confidence of the United States and some European countries...
...strikes, however, would also be difficult to carry out, since reaching the targets would be a problem for the warplanes. Israel does have aerial tankers, which would be needed to fuel the jets for the long flight to Iran and back, and its F-15s and F-16s have been conducting a lot of refueling training. For the most direct route to Iran, Israel would have to sneak its planes across Jordan and obtain fly-over rights through Iraq from patrolling U.S. jets. That means Israel would likely have to get if not Washington's approval for a strike, then...
...addition, Israel can't muster the firepower that the U.S. has, so its jets could likely handle only a limited number of targets - perhaps the soon-to-be-operating Bushehr reactor on Iran's Persian Gulf coast and the fuel enrichment plants at Natanz south of Tehran. That means the raid could only hope to set Iran's nuclear program back for several years...
...debate about where--and when--to draw that line. U.S. intelligence chief John Negroponte told TIME in April that Iran is five years away from having a nuclear weapon. But some nonproliferation experts worry about a different moment: when Iran is able to enrich enough uranium to fuel a bomb--a point that comes well before engineers actually assemble a nuclear device. Many believe that is when a country becomes a nuclear power. That red line, experts say, could be just a year away...
