A large-scale terrorist attack in Moscow has sparked controversy and discussion around the world about the identity of the killer.
Interpretations of the incident have varied, with the United States accusing ISIS of being behind the incident but denying any ties to the terrorist group, Ukraine denying the accusations, and Russia questioning the U.S. attitude.
Trump made eye-catching remarks during the campaign, saying that Obama and Hillary Clinton were co-founders of ISIS and were responsible for the terrorist attacks.
Mr. Trump's remarks sparked widespread controversy, but he insisted he made them to make America great again.
Although the outlook for the Trump and Biden campaigns is still difficult to predict, polls show Trump having a slight upper hand, while the Democrats are optimistic.
However, Trump is currently facing a series of lawsuits and fines, which could have an impact on his campaign prospects.
In response to the terrorist attack in Moscow, retired Russian military officer Andrei Prispeykin gave an in-depth analysis of the incident and pointed out that there may be a large team behind the attack.
Andrei believes that the training and planning of the attackers showed that they were different from ordinary terrorist organizations and that there could be interference from Western intelligence agencies.
In addition to the events in Moscow, the recent Pakistani terrorist attack on a convoy of Chinese engineers, in which five Chinese engineers were killed, has also attracted global attention.
These terrorist attacks are undoubtedly a serious challenge to global security, and we should remain highly vigilant and work together to deal with them.
