两大盟友之间的争议部分地反映了它们不同的当务之急：对以色列来说，红线是伊朗马上就要上马的深层地下铀浓缩设施；而对美国来说，最紧迫的问题是专门用于军事目的的核设施。
The controversy between the two allies partly reflects their divergent timelines: for Israel, the red line is Iran’s imminent burial deep underground of its uranium-enrichment facilities; for the US, it is the start of a dedicated weapons program.
