No one has ever been forced to embrace Christianity.We all have a free will to choose and dont see anything wrong with giving Bibles to anyone,irrespective of where they are on earth.
One thing i Totally Agree with in the post from the link u have given,That Jesus is the soldier’s 18-star general-Thats the bottom line.
Offer hospitality to one another without grumbling.Each one should use whatever gift he has received to serve others,faithfully administering God's grace in its various forms.
1 Peter 4:9-10
For just as through the disobedience of the one man the many were made sinners, so also through the obedience of the one man the many will be made righteous. Romans 5:19
