Firm Hillary Clinton supporter Mark Cuban has put forth his opinion on Twitter on Monday saying that if the Republican US presidential candidate wins the 2016 election, the chances of World War 3 will increase subsequently.

Cuban, who is an investor, wrote that the “ignorant” attitude of Trump is likely to enhance the level of global tensions taking pace now, thereby prompting the next world war. The speculated ignorance of the presidential candidate has been observed in terms of foreign policy handling.

The presumptive nominee’s continuous support to first nuclear strike against Islamic State and other warfare decisions makes it possible that he could lead to World War 3 if he becomes the next US president.

Recently, MSNBC host Joe Scarborough revealed that a foreign policy advisor, whose name has been kept a secret, told him that Trump has questioned why the States is not allowed to use nuclear weapons. “I’ll have to be very careful here,” Scarborough said, as quoted by The Bitbag.

“Several months ago, a foreign policy expert on international level went to advise Donald Trump, and three times he asked about the use of nuclear weapons. Three times he asked, at one point, if we have them, why can’t we use them? That’s one of the reasons he just doesn’t have foreign policy experts around him. Three times, in an hour briefing, why can’t we use nuclear weapons.”

The United States is one of the most powerful nations of the world and the election and selection there is going to influence the rest of the world. Hence, the choice of the president is expected to be done properly.

“There is nothing more important than this election right now,” Cuban tweeted. “Trump’s ignorance of the world could get us into a world war.”

The businessman, according to Business Insider, shifted to Trump’s fixing of the nation’s problems as he promised. Cuban posted a YouTube video and mentioned the “Bob the Builder” theme song and said that every Trump says that “He Can Fix It.”

Trump’s intention of handling everything using nuclear weapons might not be an acceptable initiative from the president of the United States if he becomes so. Hence, it is expected that the US presidential candidate keeps his controversial character aside and thinks in favor of the rest of the world. Otherwise, his attitude might lead to World War 3.
