Double standards by Western countries
For example, when North Korea announced their intended launch of a new rocket (which failed just minutes after take-off) there was a lot of a hullabaloo and criticism from western countries.
Yet when India announced a testing of a new long-range missile Agri 5, with nuclear capabilities and a range of 5000 kilometres, the United States, which led the criticism of North Korea, appeared to warily endorse the Indian missile launch.
