Sweden's plans during the Great Northern War had some tough problems to deal with:

• Too Big of Goals: Sweden wanted to grow its land but didn't have enough resources to support it all.
• Unreliable Friends: They relied on allies who weren't very dependable, making their situation weaker.
• Supply Problems: The lines that provided food and supplies to the troops often got blocked, which hurt their fighting ability.

To make things better, Sweden could have worked on building stronger friendships with other countries. They could have also focused on fixing their supply problems and playing more defense. This might have helped them keep the land they had gained.
