However, they faced constraints such as logistical challenges, underestimating the resilience of their enemies, and the complexities of trench warfare, which led to prolonged stalemates. Additionally, political decisions, including the commitment to maintaining strong alliances and avoiding a unilateral approach, hampered rapid military action. These factors combined to delay the anticipated quick resolution of the conflict.
