Russia bigger threat to global security than ISIS: Poland

London: Addressing a security conference in Slovakia, Poland's Foreign Minister Witold Waszczykowski has said that Russia is a greater threat to international security than the Islamic State group as it has the potential to destroy nations.

He urged NATO to protect its eastern border in the event of a Russian aggression.

“We have existential threats and non-existential threats. Of course the Russian activity is kind of an existential threat because this activity may destroy countries,” MailOnline quoted him as saying.

“And we have non-existential threats like terrorists, like massive wave of migrants. It is a very important threat but it is not an existential threat for Europe,” Waszczykowski was quoted as saying.

Poland has been Moscow's staunchest critics since the Russian annexation of Ukraine's Crimea peninsula in 2014 and its support to separatists in Ukraine.

“Presence of military troops from different NATO countries could be a symbol of determination to defend the eastern flank,” Waszczykowski said.
