I'm not sure how to respond to this. Which problems do you think most impactful in the US right now, and in what sense has he 'solved them'?
The biggest problem in the USA is the Swamp or Deep State has been trying, but has been unable to take out Trump. The Swamp is getting more and more desparate, as election time gets closer. They are creating problems hoping something well work.
If you watched the news recently, declassified information was released that showed that all of Obama's top people, swore under oath, in early 2107, that there was no proof of Russian and Trump collusion. The collusion delusion scam should never have happened. I link to the Daily Mail which is neutral in terms of the USA. This can also be found everywhere.

Later the same day the same people, who sweated under oath that there was no proof, began to systematically lie to the press. Trump has had to deal with scum bags. The under oath testimony had been made classified, so the truth could be buried from the public. Then the liars then started to lie to the press, since lying to the press is not a crime.
General Flynn is important to Trump's offense since he was framed in an attempt to take out Trump. Once he is freed of the charges he can sue all ethos who supported the scam in civil court and Flynn can hurt them in the pocket book. There is an attempt by the Democrats to delay his exoneration, for being railroaded. The Democrats were willing to hurt innocent people and still will not let it go.
Top level Democrats,all lied for three years, but they were unable to take out Trump. They had a full court press, but it all fell apart and Trump was left standing. Justice is about to be served and the Democrats and Swamp are very desparate. The only way for them to escape justice, will be if they can win the presidency and then bury the truth. They would control Justice and the FBI and evidence will disappear as priorities change.
The Democrats and Swamp know their goose is about to be cooked. Trump and some Republicans are maintaining a steam of declassified intel, that will incriminate and escalate, up to the 2020 election. If Trump wins again in 2020, the swamp will be toast. Although Durham is getting close to making criminal referrals. The rats will turn on each other.
The result is going to be increasing drama over the next months, since the alternative will be jail, civil law suits, dismissal, and a Democrat agenda that will be set back for decades. The rats are cornered and looking for a Hail Mary Pass.
The paid riots and looting, now in the news, is part of the latest attempt to take out Trump. The peaceful Floyd protests were real, but the anarchy that has taken over the front page. This is being paid for by Democrat donors. It is not coincidental that Democrats control cites have hosted the worse violence and some of these mayors still coddle the violence.
The goal is to create anarchy and then to spin this onto Trump. However, Trump is staying one step ahead of them. The Democrats seem to be willing to inflect pain on part of their base;use their pain anarchists torch black neighborhoods and business, to harden them from voting for Trump. Trump had made headway with the blacks, due to the once booming economy, that was made to stall by the Chinese and swamp bogeyman. The try to blame Trump for the hardship but it will not work as well as they think.
This much incoming requires a lot of ability to adapt, since Trump has to fight a team of cornered rats, right up to the election. Cheating is not out the question since the alternative is jail. The proxy voting and mail in voting is being resisted since this will be used to cheat.
