Trump's threat on NATO commitments could spur spending increase, says Estonian PM

"These words could potentially spur action from those who have not yet done enough in terms of defense spending. Let's hope that we will collectively enhance our efforts and stand together stronger," Kallas said during a press conference with Roberta Metsola, President of the European Parliament, who was visiting Tallinn for a day.

The EU representative also stressed that European nations need to raise defense expenditure and consistently convey a clear message "no matter who heads the next US administration," indicating that Europe is capable of defending itself.

"We should perceive these statements as an indication of the potential threat they pose. However, regardless of the situation, we must remain firm in our efforts," Metsola added.

Former US President Donald Trump recalled a conversation with the head of a NATO member country during a Saturday rally in South Carolina:

"The president of a large country asked me, 'Sir, if we don't pay and Russia attacks us, will you come to our aid?' I replied: 'No, I won't protect you. In fact, I would encourage them (Russia) to proceed as they wish. You must make your payment'."

Estonia's budget for 2024 has allocated 3.2 percent of its GDP for defense- a figure greater than the 2 percent requirement stipulated by NATO.
