"What Saudi Arabia did by occupying Bahrain was not and is not a difficult and important thing to do," Kharrazi said on Saturday.
"If Iran wanted, it could take control of Bahrain in a few hours by using its rapid reaction forces," he added.
"But, these methods do not conform to Iran’s logic," Kharrazi said, and added that "Iran wants security for the Persian Gulf and we showed the same policy during Saddam Hussein’s era. Yet, if Saudi Arabia wants to enter a different game, it will certainly be fragile" (to Iran’s response).
Six Persian Gulf Arab states strived at a summit last month to forge closer political and military union which would start with a practical annexation of Bahrain to Saudi Arabia, but the talks ended inconclusively after the Bahraini people and other nations voiced strong opposition to the plan.
No agreement on further integration emerged as smaller Persian Gulf Arab states are wary of the Saudi domination of the region.
In the run-up to the Riyadh meeting, speculation was rife that an initial union would be announced between Saudi Arabia and Bahrain, where anti-government protests led by majority Shiites have gripped the island state since last year.
Riyadh has aided Bahrain’s embattled Sunni monarchy with troops and money during the island nation’s 15-month uprising.
Bahrain has been hit by near daily protests and clashes since the uprising began in February 2011 inspired by revolutions in other Arab countries. People seek an overthrow of the Al-Khalifa’s over-40-year rule over the tiny Persian Gulf island. At least 69 people have been killed by the Manama regime, where a Saudi-led Persian Gulf force came to the aid of the ruling dynasty last year.
Majority Shiites have been leading a pro-democracy uprising in Bahrain for over a year. Saudi Arabia, fearing that unrest in Bahrain could spread to its own Shiite community in its major oil-producing Eastern Province, sent troops to Bahrain last year to help its government crush the initial phase of the revolution.
The Bahraini people call the unity proposal a sellout of the country’s independence and an effort to give Saudi security forces a stronger hand in crackdowns in the strategic island kingdom, which is home to the US Navy’s 5th Fleet.
