最后还有两个因素：欧元区经济多快见底（最近已出现一些稳定信号，但该货币联盟的长期顽疾并未解决 ） ； 以及中东紧张局势和核扩散危险 — — 以及美国和以色列对此威胁的应对 — — 会逐步升级还是成功遏制。
Two final factors include how soon the eurozone economy bottoms out (there have been some recent signs of stabilization, but the monetary union’s chronic problems remain unresolved), and whether Middle East tensions and the threat of nuclear proliferation in the region – and responses to that threat by the US and Israel – escalate or are successfully contained.
