What does Oli mean by ‘big action’?

It may indeed mean some drastic moves. But since he often employs such tactics, as is his wont, it may also mean nothing but just a ploy to threaten his opponents, insiders say.

Despite being pressured and cornered, Nepal Communist Party chair KP Sharma Oli, also the prime minister, has refused to relent. Instead, according to insiders, when the other chair Pushpa Kamal Dahal pressed him for party meetings, he said in response that meetings are not required and even if any decision is taken against him, he would rather make a counter move–that he will take a “big action.”
