The next president of the USA must handle several crises simultaneously. What does it mean for the security situation if Trump wins? Here, three experts answer.
Ukraine
For Ukraine, the situation looks much darker with Trump as president than with Harris, according to Magnus Christiansson, a war researcher at the Defence University.
He points out that Trump has promised to fix peace in 24 hours.
It will not be resolved in 24 hours, and I think everyone understands that. Without this statement, it's more about Trump being willing to compromise with Putin, says Christiansson.
The "peace plan" presented so far involves a demilitarized zone where occupied territory would be handed over to the Russians. Trump has also signaled on several occasions that he wants to reduce support to Ukraine.
There is a risk that Trump tells the Ukrainians that if you don't sit down with Russia, you won't get any weapons and ammunition. It could also mean the end of the war, if Ukraine is militarily defeated.
NATO
Magnus Christiansson finds it difficult to see Trump withdrawing the USA from NATO. However, Trump is likely to scale down engagement in Europe. Concerning is also Trump's statement that NATO countries "must pay their bills".
That means, for countries that pay 2 percent of GDP, Article 5 applies, but others will have to wait in line. It's a way to crack the entire alliance and ruin NATO's defense planning, says Christiansson.
He emphasizes that the decisive factor will be who Trump chooses to surround himself with. During the previous term, when Trump declared NATO "obsolete", his Defense Minister James Mattis simultaneously strengthened the American presence in Europe.
Middle East
Both Trump and Harris have good opportunities to achieve a ceasefire in the Middle East, according to Anders Persson, a political scientist at Linnaeus University with a focus on the region.
They will put a lot of effort into it, and Israel will be eager to get a good start with the next president. The question is what a ceasefire will contain and how long it will last.
A risk is if Trump continues to be as pro-Israeli as during his previous term, he believes.
Some think Trump will give Israel the green light to ethnically cleanse Palestinians in northern Gaza and allow Israel to annex the West Bank. I'm not at all sure it will be like that, and one reason is Trump's bad relationship with Netanyahu during the latter part of the previous term, when he felt betrayed.
The chance for a long-term peace in the Middle East is simultaneously greater with Trump, Persson believes. He points, for example, to Trump's ability to expand the Abraham Accords (peace agreements between Israel and several Arab countries), which he previously mediated.
But also that he is unconventional, maybe a little crazy, he has qualities that other politicians don't have.
China
Last time Trump was president, he started a trade war against China, and there is also a risk of increased tensions now, according to Björn Jerdén, head of the National Knowledge Centre on China at the Foreign Policy Institute.
Trump has, for example, said that he will introduce very high tariffs on Chinese exports to the USA.
At the same time, China's aggressive behavior towards Taiwan continues. Jerdén believes, however, that American support for Taiwan will remain intact regardless of who becomes president.
The risks of a greater change in either direction are so great that a president would likely act like their predecessors and not challenge.
Trump may, however, pressure Taiwan to pay more for its defense.
At the same time, Jerdén does not believe that the risk of China attacking Taiwan increases with Trump at the helm.
We know very little about exactly how China's leaders reason. But it's rather the military balance of power that is decisive, than whether it's Trump or Harris who is president.
