Paraguay believes FARC has set up shop in the country. As a result, the government has allowed the army to receive support from the Colombian Army in training and intel ops. This makes three countries outside of Colombia in which FARC is operating, Venezuela (perhaps with the tacit consent of the leftist government), Ecuador, and Paraguay. Of the three, Paraguay does not border on, nor is particular near, Columbia.
While FARC is getting hit hard, it has lots of money, thus it has options. Moving operations to other countries is one option. There's no doubt FARC is rich. As more FARC camps are overrun, captured equipment includes GPS systems, digital mapping equipment, computers of all sorts, SATCOM equipment, and so on.
