Another important factor to consider is the methods used by each movement to achieve their goals. Some movements engage in peaceful protests and advocacy, while others resort to violence and terrorism. The use of violence raises serious ethical concerns and undermines the legitimacy of any movement’s claims.

Ultimately, any assessment of the validity of claims made by nationalist and ethnic separatist movements must be made on a case-by-case basis. There is no single answer that will apply to all movements.

In terms of similarities and differences between the ETA and the LTTE Tamil Tigers, both groups were ethnically-based separatist movements that used violence to achieve their goals. However, there were also some key differences between the two groups. The ETA was a Basque nationalist movement that aimed to establish an independent Basque state in Spain, while the LTTE was a Tamil nationalist movement that sought to create an independent Tamil state in Sri Lanka. Additionally, the ETA was active for over 60 years, while the LTTE was only active for about 30 years.

It is important to note that these are just some of the factors that can be considered when assessing the validity of claims made by nationalist and ethnic separatist movements. There is no easy answer, and any attempt to rank these movements would be subjective and open to debate.
