The British newspaper reported that Trump proposed the plan as a fallback solution after promising that US military units would not be deployed in Ukraine as part of security guarantees.

Instead, private American companies could deploy their soldiers to help build Ukrainian frontline defenses, protect new bases built near the front, and protect American business interests.

"Forefront fortifications and bases in the vicinity could be built by American private military contractors, just as they were in Iraq and Afghanistan," the newspaper claims, adding that European powers would see this as significant support. The presence of these companies in Ukraine would also act as a deterrent against another Russian invasion.

The US is discussing the plan as part of a broader discussion on possible security guarantees for Ukraine, which is being worked on by a so-called coalition of the willing led by the UK and France. The possible deployment of the aforementioned American companies began to be discussed after the US and Ukraine signed a mineral resources agreement at the end of April.

Security guarantees, rearmament of Ukraine and NATO training

According to the newspaper, Ukraine's European allies began working much more intensively on the final security guarantee plan after Trump told them that Russian leader Vladimir Putin had agreed to Western allies providing security guarantees to Ukraine during a joint meeting in Alaska in August.

The Coalition of the Willing has long argued that the main strategy for future deterrence is to build a strong Ukrainian army to protect the front lines after a ceasefire. Ukraine would be rearmed and its soldiers would receive training from European NATO countries. At the same time, Kiev would continue to have the opportunity to purchase American weapons through its European allies.

Some European countries are proposing the creation of a buffer zone between Ukrainian and Russian positions after a ceasefire is signed. According to the newspaper, Ukrainian President Volodymyr Zelensky is expected to demand the presence of European troops in the zone, while Trump has spoken about the possibility of China participating.

If the Russians invade Ukraine again, we will fight on their side

There has also been long-standing talk of deploying European troops inside Ukraine in case the Russians break the ceasefire and resume their invasion. “The main goal is to show the Ukrainians that if Russia invades their country again, we will fight alongside them,” a European official told the newspaper, speaking on condition of anonymity.

According to the newspaper,"several dozen countries" such as Britain, France, Germany, Belgium, the Baltics and Scandinavian countries would like to participate in this operation. Previously, there was talk of 30,000 soldiers, but this number was reduced due to a lack of resources and also to avoid being perceived as"too strong" in the eyes of Putin.

According to the newspaper, these forces would be deployed in Ukraine for five to ten years, or until the European allies are confident that the Ukrainian army is strong enough to stop the Russians on its own if necessary.

But as the newspaper pointed out, the most likely scenario is that European troops would be deployed more to western Ukraine, where they would train Ukrainian soldiers. French President Emmanuel Macron was the first to suggest this last year, but then-US President Joe Biden rejected it, saying it would be an escalation.

Another point of discussion on security guarantees is the introduction of a no-fly zone that would allow Ukraine to safely resume commercial flights. This plan would be implemented gradually, with flights initially to western Ukraine, such as Lviv, and over time, flights would begin to flow further east, including Kiev.

"The resumption of air travel is seen as a key element in reviving investment in the war-torn country and would also help refugees return home," the newspaper notes.

The plan also calls for Turkey to lead a naval mission in the Black Sea to secure trade routes to and from Ukraine. The mission, supported by Black Sea states Bulgaria and Romania, would also lead efforts to demine the waters.

Putin cannot be trusted and everything depends on the Americans

Any deployment by European allies is dependent on assistance from the United States. The newspaper says that logistics will need to be secured with American aircraft to transport the necessary equipment and troops eastward into Ukraine.

However, American intelligence is also important because Europe does not have the necessary satellite capabilities to monitor compliance with the ceasefire.

European and American officials are also discussing having an American commander lead all security assurance operations, as Europe lacks the necessary experience in coordinating large military missions.

In addition, Europe is also demanding that its troops from Poland and Romania be covered by American fighter jets, which, according to the newspaper, is one of the main demands for Donald Trump - to deploy more American fighter jets and American missiles in Europe, which would be activated immediately after Russia violates the ceasefire.

But European officials fear that any talk of guarantees for Ukraine will be futile because they believe Russian leader Putin has no real interest in a ceasefire. Many believe Moscow is playing Trump's hand in the negotiations and the Russians' real goal is to seize more territory in Ukraine.
