I would like to point out to everyone underestimating Portugal’s influence in world politics that, while I agree it hasn’t been a military or economic major power in centuries, it has great diplomatic outreach:

• Part of the EU and has been used as an example of how to handle drug abuse
• Part of CPLP which seeks to align the interests of all Portuguese speaking countries (in Europe, South America, West and East Africa and Oceania)
• Vast naval territory in the Atlantic and the Azores which have hosted a US military base for decades
• Good relations with China especially after the return of Macau
• The current secretary general of the UN is an old portuguese Prime Minister

So while no longer a major country, it still has sway on how relations between some countries develop
