Yeah it's true and it's politics indeed, Whoever is strong with some resources he uses those cards.

In international politics and relations cards are also played.
recently in America Pakistan used many many cards, Afghan, Taliban card, Nuclear Card. Pakistan sometimes uses China card. Same way India always uses its big economy (huge population) card. Saudia plays oil card.
