Former Colombian President Álvaro Uribe this week voiced his strong opposition to the tentative agreement his successor, Juan Manuel Santos, has struck with the country's leftist guerillas.

The deal undermines the rule of law in Colombia, and the it gained from the international community suggests a double standard as the United States and European nations in the past have advocated jail time for terrorists from the Spanish separatist group ETA, the Irish Republican Army and other militants, Uribe told the Associated Press.

But "I'm more worried about what Colombians think than the international community," the former president noted, "because we are the ones who are going to have to live with the consequences of what's happening."

Uribe, who led the South American nation from 2002 to 2010, had been critical of the talks with the Revolutionary Armed Forces of Colombia (FARC) from the start, the Argentine news agency Télam reported. And when Santos and FARC commander Rodrigo Londoño announced a breakthrough in the long-running negotiations last week, he warned that deal would likely lead to "more violence in Colombia."

The Oxford-educated Uribe has since been waging what the Washington Post called a "one-man Twitter war" against the agreement and warned that its terms would amount to "a new dictatorship backed by guns and terrorist explosives."

Uribe also did not shy away from going after U.S. Secretary of State John Kerry, who had praised the rapprochement along with many other top diplomats from around the globe.

"(It is) deplorable that Secretary of State (John) Kerry would applaud an impunity deal with the FARC that would never be accepted with (the Islamic terrorist group) al-Qaida," the former president wrote.

Meanwhile, Uribe -- whose father was killed by the FARC in a botched kidnapping attempt in the early 1980s -- told the AP that Londoño's refusal to apologize to the their victims in a TV interview this week marked yet another affront impeding a final reconciliation.

"More than standing up for victims, he's offending them," he noted.
