Just How Bad Is The Iranian Nuclear Agreement?

The deal that our Dear Leader, President Obama, and our illustrious secretary of state, John F. Kerry, reached with Iran to supposedly end Iran's quest for a nuclear bomb is as bad as thought.
If you dare to look at this link, and FTR, I am NOT a lawyer, the pages 11 through 17 is the crux of the deal and it deals with all of the economic sanctions that, until now, had the Islamic Republic of Iran on the ropes. It is a bonanza for both Western multinational companies and especially an economic lifeline for the mullahs in Iran.
But if we go back to page three of the agreement, this is what is supposed to happen:

Iran reaffirms that under no circumstances will Iran ever seek, develop or acquire nuclear weapons.

Successful implementation of this JCPOA will enable Iran to full enjoy it's right to nuclear energy for peaceful purposes under the relevant articles of the nuclear Non-Proliferation Treaty (NPT) in line with it's obligations therein, and the Iranian nuclear programme will be treated in the same manner as that of any other non-nuclear weapon state party to the NPT.

Seems pretty cut and dry and that Iran is going to give up it's quest for a nuclear bomb, right? But what, what if there is any suspicion that Iran maybe using other means to attain a nuke? Is there any way to find that out?
Not particularly. If you read the first section, numerous times it refers to both sides agreeing to "voluntary" implementation of the deal. As I read it, again I am not a lawyer nor an expert on treaties, it appears that it can take up to 45 days to resolve any disputes of the treaty. That would include inspections as well, no? Thus if there is any suspicion that Iran was not living up to it's end of the deal in relation for nuclear development, we can't get in a timely manner to verify and thus Iran can simply buy time to hide what it is really doing.
Again, if you take time to read this, it appears that Iran gets all of the advantages and a boatload of business to prop up the Shia Islamic regime.
And in the end, nothing to really stop the Iranians to develop and or purchase on the black market, a nuclear device. All they need is to have one, no matter what condition, to make trouble in the region.
This is a bad deal for all except for the nation of Iran. Maybe that is what Western leadership has wanted all the way around.
