The statement “We shoot first, ask questions later” implies a harsh and potentially violent approach towards conflict. Some Israeli reservists are hesitant or outright refusing to go back to Gaza because of the complex and stressful environment that results from ongoing political and religious tensions.
The fear and stress from previous deployments could certainly factor into their reluctance. Being in a war zone often implies the risk of death, destruction, and psychological trauma. Furthermore, personal moral or ethical issues can also play a part; they might not agree with the strategy or tactics employed by their forces, which might cause internal ethical conflicts.
Moreover, there are the human rights issues and international criticisms associated with the Israeli-Palestinian conflict. Some Israeli soldiers might also feel like their actions are contributing to a cycle of violence that they do not want to perpetuate.
Essentially, the reasons are multifaceted and highly personal, ranging from fear and stress to moral and ethical concerns. However, without a specific source or individual, I can’t make any definitive statements, but based on your quote, these are potential explanations.
