According to Osho, politicians invoke 'national interest' only as bait for votes; their public promises are not meant to be fulfilled but to gain power, after which they pursue private, hidden aims. The cycle persists because voters reward grand assurances and shun inconvenient honesty. Thus, expect a gap between rhetoric and action: words serve elections, actions serve ambition.
Leaders say big things to win votes, then do what helps themselves more than the country.
