Arthur, you look but don’t see, otherwise you would not ask what problems humanity faces. The first that comes to mind is Climate Change, something the ‘Strawman’ Trump does not believe in, despite 97% of the world’s scientists agreeing that it is both happening and is human induced. https://climate.nasa.gov/scientific-consensus/
The fact that Trump lost the popular vote (the vote that counts in most democracies) and that the racially motivated ‘Electoral College’ ruled against that vote. Secondly, it is common knowledge that Russia interfeared with the 2016 presidential Election:
Reports of the DNC’s early suspicions
“Nearly two months earlier, in April, the Democrats had noticed that something was wrong in their networks. Then, in early May, the DNC called in CrowdStrike, a security firm that specializes in countering advanced network threats. After deploying their tools on the DNC’s machines, and after about two hours of work, CrowdStrike found ‘two sophisticated adversaries’ on the Committee’s network. The two groups were well-known in the security industry as ‘APT 28’ and ‘APT 29.’ APT stands for Advanced Persistent Threat — usually jargon for spies. CrowdStrike linked both groups to ‘the Russian government’s powerful and highly capable intelligence services.’ “ — Motherboard, July 25, 2016
Intelligence agencies report to President Obama
“American intelligence agencies have told the White House they now have ‘high confidence’ that the Russian government was behind the theft of emails and documents from the Democratic National Committee, according to federal officials who have been briefed on the evidence.” — New York Times, July 26, 2016
State voting registration systems hacked
“Nearly half of the states in the U.S. have recently had their voter registration systems targeted by foreign hackers, and four of those systems have successfully been breached, sources tell ABC News.
“That amount of targeting and actual infiltration into state election-related systems is significantly larger than the U.S. government has been willing to acknowledge.
“Hackers working on behalf of the Russian government are suspected in the onslaught against more than 20 state election systems, according to sources with knowledge of the matter.” — ABC News, Sept. 29, 2016
Donald Trump is not fit to serve as a US President and will soon be forced to resign because he is a strawman (lacking in integrity and substance). He has damaged the USA in its relationships with almost every other country on Earth and as a result, has retarded any hopes the US has of engaging in the new and emerging economies, to the detriment of the American people ‘Dude’.
