Ukraine: The 4 Scenarios for Security Guarantees from the US

Following talks at the White House regarding Ukraine, the form of US security guarantees is the question. Donald Trump is reportedly willing to participate in these guarantees, but the landscape remains unclear.
In a BBC analysis, 4 scenarios are presented:
- Ground troops: Considered the least likely scenario.
- Air and sea patrols: A more likely scenario, given that the US already conducts surveillance flights.
- Intelligence: US satellite and aerial intelligence is crucial.
- Logistics: Logistical support to a UK/French-led 'security force'.
The BBC emphasizes that Zelensky gained time from the talks, while German Chancellor Friedrich Merz and French President Emmanuel Macron supported a ceasefire in Ukraine.
