• NATO's crisis management and cooperative security tasks may be reassessed.
• The US may reduce its role in these tasks, potentially shifting burden to Europe.
• Europeans could take more responsibility for crisis management and cooperative security.
• This shift could impact NATO's collective defence and the European pillar.

The potential US withdrawal from crisis management and cooperative security tasks may indicate a shift in NATO's priorities, which could suggest a more balanced burden between the US and Europe. This development may also imply that Europeans will take more responsibility for their own security, which could lead to a stronger European pillar within NATO.
