"But more than that, it is to save the country from total destruction".
Lopez was released from prison July 8 and placed under house arrest after serving three years of a 13-year sentence on charges of inciting violence at opposition rallies.
"These attacks, planned by delirious minds in Miami, only strengthen the morale of our armed forces and the Bolivarian people", said Socialist Party official Elias Jaua.
More than ten countries of the region, among them Argentina, Colombia, and Peru, said that would not recognize the electoral results.
The South American has for months been in the throes of a political crisis with protests that have left more than 100 dead, almost 2,000 wounded and over 500 detained.
Authorities in Venezuela have announced they thwarted a "terrorist attack" on a military base not far from the capital, Caracas.

Sources described the suspect as a French national born in Mauritania, western Africa, who left a psychiatric hospital in July. Monuments in the French capital are occasionally evacuated for security reasons as part of those measures.
Lopez had been arrested along with another opposition leader, Antonio Ledezma - who was released back to home detention Friday, August 4 - in the aftermath of the highly contested vote to create the assembly.
Maduro contends that the assembly is the solution for Venezuela's political standoff and dire economy. "The only thing it's doing is destroying itself and committing suicide".
On Saturday, the South American trade bloc Mercosur moved to suspend Venezuela for failing to follow democratic norms.
"I denounce this arbitrary act before the national and worldwide community", she said.
"The suspension of Venezuela was applied due to the actions of the Nicolas Maduro government and is a call for the immediate start of a process of political transition and restoration of democratic order", according to a statement issued in Sao Paulo, where foreign ministers of the four countries met Saturday.
The results have come under mounting scrutiny after the worldwide company that provided the electronic voting machines said that "without any doubt" the official turnout had been tampered with a charge dismissed by Maduro and the National Electoral Council. Venezuela's socialist party (PSUV) leaded by Hugo Chávez implemented an anti-capitalist revolution ("La Revolución Bolivariana") when it came to power in 1999, and since then the party has destroyed Venezuela's democracy up to the point of emulating totalitarian governments such as Bashar al-Assad's in Syria, Kim Jong-un's in North Korea, and Robert Mugabe's in Zimbabwe. But the agenda is expected to be set by bigger-name loyalists, including Maduro's wife, son and several Cabinet ministers who resigned to join the body.
Maduro in turn has granted it vast powers, not just in military matters but over key government ministries - active or retired officers head 12 of 32 ministerial posts - and in vital economic sectors including petroleum.
