### Comment:
The ELN, a Colombian rebel group, has already taken over large swaths of the southern part of the country to secure control of various gold mining operations there. Its not clear how they would react towards any attempt to overthrow the government, but they benefit from the regime's control over Venezuela and would likely oppose any attempt at removing the government from power.

Could Columbia declare war on Venezuela over harboring these rebels?
