US Ambassador to Israel Dan Shapiro has called on Israeli Prime Minister Benjamin Netanyahu to prepare for the day after Congress votes in favor of the Iran nuclear agreement.
He, however, said Tel Aviv should cooperate with Washington despite disagreement between Netanyahu and President Barack Obama.
"We have to accept that there is a clear disagreement between us and maybe we won't succeed in convincing each other," Shapiro told Israeli radio on Monday.
The envoy also said he offered the Israeli leader to open “diplomatic talks on how we can increase our security cooperation to deal with outcome of the Iranian deal.”
Israel needs to discuss “what intelligence information we need, to come to an agreement regarding military assistance that may be needed in the next ten years,” he said.
"Until now the prime minister hasn't agreed to have these conversations. I believe the time has come," Shapiro said.
"It is not productive for us just to argue...we can still begin to prepare for the day after. We will need to work together to deal with Iran so why not prepare for it," he added.
After the conclusion of nuclear negotiations between Iran, the US, and its five partners in Vienna last month, Congress is scheduled to vote on the agreement in September.
Republican lawmakers have expressed their opposition to the deal, but Obama is hopeful that his fellow Democratic allies in both chambers support him.
On Sunday, President Obama once again criticized Netanyahu for failing to present a better alternative to the negotiated nuclear agreement.
“I’ve repeatedly asked both Prime Minister Netanyahu and others to present me a reasonable, realistic plan that would achieve exactly what this deal achieves, and I have yet to get a response,” he said.
