US President Barack Obama has given an extraordinary ultimatum to the Republican-controlled Congress, arguing that they must not block the nuclear accord with Iran. It’s either “deal or war,” he says.

In a televised nationwide address on August 5, Obama said: “Congressional rejection of this deal leaves any US administration that is absolutely committed to preventing Iran from getting a nuclear weapon with one option: another war in the Middle East. I say this not to be provocative. I am stating a fact.”
