Is IAEA reliable on preventing Iran to achieve his atomic bomb?

The Associated Press reported on August 19, 2014 that it has seen a document showing Iran will be allowed to use its own experts to inspect Parchin site which is allegedly used to develop nuclear arms under a secret agreement with the IAEA. 

This shocking news increased worries if U.S. and IAEA promises on the Iran deal can be trusted or not? Obama administration has repeatedly announced that Iran deal is based on verification and not trust of Iranian regime. But now it seems that the named ‘verification’ is also done by Iranian experts. It is pretty much the same as we ask a murderer to verify if he killed somebody.

On August 20, IAEA chief Yukiya Amano said in a statement, 'I am disturbed by statements suggesting that the IAEA has given responsibility for nuclear inspections to Iran'. He added the IAEA’s arrangements with Iran are 'technically sound and consistent with our long-established practices. They do not compromise our safeguards standards in any way.'

Looking at the history of IAEA makes more doubts about credibility of IAEA and what it calls IAEA’s ‘long-established practices.’ How anybody can be sure that Iranian regime will not ‘compromise IAEA’s safeguards standards in any way’.

In the past 20 years, at the presence of the IAEA, India, Pakistan and North Korea have all openly tested nuclear weapons. Nuclear facilities have been discovered in Libya, Iran, and Syria without even IAEA knew about.

Since the 1970s, network of father of Pakistan’s nuclear bomb, Khan, has provided nuclear knowledge to Libya, Iran, North Korea and Pakistan. When Khan was finally arrested in Pakistan in 2004, the IAEA never gained access to or debriefed the man.

IAEA Director General Yukiya Amano also stressed that 'IAEA resources are limited.' IAEA admitted on its 2010 report that 'the IAEA is fighting tomorrow’s wars with yesterday’s tools.'

The White House has denied claims by critics that a secret 'side deal' favorable to Tehran exists. If so, why there have been 'seven different answers from members of the administration' on whether or not administration officials have read or been briefed on the agreements between Iran and the International Atomic Energy Agency (IAEA), as written on a letter from Sen. Tom Cotton of Arkansas and Rep. Mike Pompeo of Kansas to Secretary of State John Kerry.

So can anybody still believe that the IAEA, with its secret side deal, and the Iranian nuclear deal in general, are capable of stopping Iran from acquiring the nuclear bomb?
