In 2002, Spain's Ministry of Defense's Juan Miguel Lian Macias gave a speech at a NATO seminar regarding ETA. He stated that ETA had been gaining control of weapons in Western countries before the collapse of the Soviet bloc in the East. As a result of the break up of communism, ETA transitioned towards these countries for weapons. He also mentioned that new information was suggesting that ETA cells were starting to evolve in Latin American countries. Macias' speech asserted that his government was actively combating ETA as a terrorist organization, and brought awareness of the groups power to the international arena. (You can find the source to the speech in the bibliography.)

ETA declared a ceasefire in 2011 and has not been violent since that time. (Miller, Erin, and Kathleen Smarick. 2011. "ETA Ceasefires by the Numbers." October 21.) However, they are still considered a terrorist organization by the Spanish government, and remain distant from governmental affairs. Government involvement and recognition have been some of the grievances of ETA therefor considering them in policy making could be beneficial for the Spanish government. (Ibid.)

ETA is believed to still be heavily armed with bombs and other military equipment. Therefore Spain should keep watch for possible small acts that could be part of another reign of terror by ETA. Spanish domestic counterterrorist policies should include gaining as much information as possible on individual ETA members so they can be watched and to ensure multiple ETA affiliates aren’t interacting with each other. Known members could be restricted from traveling to certain parts of the country, or restricted internationally. This would be beneficial to combating a potential international ETA threat. 

The United States would benefit from keeping their attention on ETA, but no real action needs to be taken at this time. ETA has not been violent in the last four years. ETA is a nationalist movement based in Spain, therefore the violence would be expected to stay within Spanish borders. ETA remains a recognized terrorist organization by the US government, however they could be removed until they are a bigger threat. However with mentions of potential cells in Latin America, it could be understood why they are still on the list.
