You are such an ignorant fool. Team sports have a reduced number of countries taking part in the olympics because there is not enough time within two weeks to make a tournament with a large pool. The soccer world cup, for instance, requires a full month to host a 32 teams tournament. So instead, for the olympics there are pre-olympic tournaments all over the world that award the qualifying spots. Loads of countries do take part in these pre-olympic tournaments.
FWIW, in the history of the olympic field hockey competition, even though it used to be dominated by India, there have been olympic medalists from all continents: North and South America (USA and Argentina), Africa (Zimbabwe), Oceania (Australia and New Zealand), Asia (India, Pakistan, China, South Korea and Japan) and Europe (Netherlands, Germany, UK, Spain, Czeckoslovakia, Denmark, Belgium, Russia). That sounds pretty global to me.
The only sport that arguably does not deserve its spot in the olympics is men's soccer, as it is the only olympic sport where the very best players in the world do not take part in the competition. Every other sport where the very best in the world compete is worthy, imo.
