Q – Shouldn’t Christians bless and help Israel fight her enemies?
A –
Jesus teaches and commands people to love and bless everyone, 
including ---especially --- their enemies.
Matthew 5:43-48 (CEV)
43 You have heard people say, “Love your neighbors and hate your enemies.” 44 But I tell you to love your enemies and pray for anyone who mistreats you. 45 Then you will be acting like your Father in heaven. He makes the sun rise on both good and bad people. And he sends rain for the ones who do right and for the ones who do wrong. 46 If you love only those people who love you, will God reward you for that? Even tax collectors[a] love their friends. 47 If you greet only your friends, what’s so great about that? Don’t even unbelievers do that? 48 But you must always act like your Father in heaven.
