"More slack will come when South Africans are not ready to expropriate land because they are afraid of sanctions, they are afraid of kickback – do not vote for EFF," Malema told a press conference.
"If you vote for us, we will expropriate land Donald Trump will come for us Britain will come for us The EU will come for us," he said.
He made the statement after the American president Donald Trump had ordered his secretary of state to carefully study the movements of the constitution for the expropriation of land without compensation and killing farmers.
The announcement by Trump came months after the civil society organization AfriForum mobilized international support.
Malema said that Trump had not said anything extreme, but he was adamant that things still had to come, including murders, sanctions and poverty.
"I hope the Zuma group knows the consequences, we know the consequences," he said.
"We know that the first reaction will be murders and they will kill us for this, a group of white right-handed people trained by Jews in Pretoria to be snipers," Malema said.
He also said that the Trump tweet made the EFF more determined to expropriate land without compensation.
"We know the consequences of what we ask, it is not that we go to these things without knowing the consequences, if someone is in this thing without knowing the consequences, then you are in the wrong place."
He also said that they were suspicious that the DA and the ANC camp, in agreement with President Cyril Ramaphosa, share the same opinion as Afriforum to "lobby for international support so that we develop cold feet".
"They want to use these kinds of threats to get out of this thing, we must never be fooled, we are not kids," he said.
Recalling a session at the National Assembly on Wednesday, Malema said that Ramaphosa, whom he described as having lost contact with the people, explained to himself the expropriation of the country.
"It's the hardest to explain a policy you do not believe in. How do you say you have to dispropriate people and give property deeds?", He said again, and rejects the idea of giving people property deeds if land is expropriated .
Malema also said that they welcomed the start of the Zondo Committee of Inquiry on State Collection, despite their concerns that the former AG Terence Nombembe is part of the team.
"We will leave everything in God's hands, everything is possible, Nombembe is part of those arrangements," he said.
"We have no confidence in Nombembe, but there are some individuals with a good reputation and credibility.
"Those are people who offer us some comfort," he said.
Malema said that the way in which Judge Raymond Zondo dealt with the EFF's concerns about Nombembe made them suspicious.
"We have not yet reached a conclusion about Zondo, but, you know, we are very careful around him, time will tell."
