They have a lot of soldiers and rockets/missiles, and their leaders can be quite fanatical as shown by the Iran-Iraq War.
Some decent quality jets, including the old US F-14s, as well as some newer models too from various nations, including those that fled from Iraq.
Their navy is very weak, but they do have a lot of speedboats. Some of them are probably equipped, or can easily equipped with large amounts of explosives, making them into crude suicide boats.
Water-skiing anyone?
"Iran does not currently have a nuclear weapons programme, and has previously said it does not want one. But it does have many of the elements required and the knowledge to create a military nuclear capability.
In 2015, the US government under President Obama estimated that Iran only needed two to three months to produce enough nuclear material to make a weapon".
The statement above about their lack of a nuclear weapons program is just patently false, despite assertions to the contrary. Statements from Iran's leaders in the last 24 hours demonstrate that, as well as US negotiations and payments under the previous administration to forestall that until our last guy was out of office.
They don't have so many people and "secret" underground facilities working on refining uranium to high levels, and ICBMs for medical research, and/or putting satellites into orbit. They can hire people to do the latter far more affordably than doing it themselves. Also, the Israelis captured a cache of documents about their nuke weapons in a daring commando raid against a virtually unguarded facility a few years back too.
The jury is out on whether they have nukes or not.
They've been saying that Iran could have nuclear warheads in 3 – 6 months for the last 20 – 25 years, so by that measure, they could have more than a couple of dozen, low-yield, crude weapons, and/or dirty bombs now.
Here's a link to info about the daring Israeli raid, and what they uncovered:

Here are a couple of brief excerpts from the article:
"The papers show these guys were working on nuclear bombs".
"The Iranian program to build a nuclear weapon was almost certainly larger, more sophisticated and better organized than most suspected in 2003, when Project Amad was declared ended, according to outside nuclear experts consulted by The Times. Iran had foreign help, though Israeli officials held back any documents indicating where it came from. Much was clearly from Pakistan, but officials said other foreign experts were also involved — though they may not have been working for their governments".
